Assignment 1: Bottling Company Case Study

Due Week 10 and worth 140 points

Imagine you are a manager at a major bottling company. Customers have begun to complain that the bottles of the brand of soda produced in your company contain less than the advertised sixteen (16) ounces of product. Your boss wants to solve the problem at hand and has asked you to investigate. You have your employees pull thirty (30) bottles off the line at random from all the shifts at the bottling plant. You ask your employees to measure the amount of soda there is in each bottle. Note: Use the data set provided by your instructor to complete this assignment.

Bottle Number	Ounces	Bottle Number	Ounces	Bottle Number	Ounces
1	14.23	11	15.77	21	16.23
2	14.32	12	15.80	22	16.25
3	14.98	13	15.82	23	16.31
4	15.00	14	15.87	24	16.32
5	15.11	15	15.98	25	16.34
6	15.21	16	16.00	26	16.46
7	15.42	17	16.02	27	16.47
8	15.47	18	16.05	28	16.51
9	15.65	19	16.21	29	16.91
10	15.74	20	16.21	30	16.96

Write a two to three (2-3) page report in which you:

1. Calculate the mean, median, and standard deviation for ounces in the bottles.
2. Construct a 95% Confidence Interval for the ounces in the bottles.
3. Conduct a hypothesis test to verify if the claim that a bottle contains less than sixteen (16) ounces is supported. Clearly state the logic of your test, the calculations, and the conclusion of your test.
4. Provide the following discussion based on the conclusion of your test:

1. If you conclude that there are less than sixteen (16) ounces in a bottle of soda, speculate on three (3) possible causes. Next, suggest the strategies to avoid the deficit in the future.

Or

1. If you conclude that the claim of less soda per bottle is not supported or justified, provide a detailed explanation to your boss about the situation. Include your speculation on the reason(s) behind the claim, and recommend one (1) strategy geared toward mitigating this issue in the future.

Nonlinear Systems and Control

⦁ Sliding Mode Control Warm-Up We will work on the system
x˙1 = x2 + ax1 sin(x1)
x˙2 = bx1x2 + u (1)
where a and b are unknown constants, but we know that 0 ≤ |a| ≤ 2 and 1 ≤ |b| ≤ 3.
⦁ Show that this system is state feedback linearizable. Assume that aˆ = 1 and ˆb = 1.5 are nominal values of a and b that you will use for your feedback linearizing controller; furthermore, assume for now that a = aˆ and b = ˆb. Simulate your controller by regulating the states to zero.
⦁ Now suppose that a 6= aˆ and b 6= ˆb, and that the real values of a and b are a = −1, b = 2. Using Matlab, plot the phase portrait of the open-loop system (1), and identify the regions where the system exhibits different behaviors.
⦁ Explain why it is not possible anymore to use your controller from (a) when a 6= aˆ and b 6= ˆb and guarantee convergence to zero. In particular pay attention to the diffeomorphism and the controller itself. Verify by setting a = −1, b = 2 in your simulation with the same u and diffeomorphism you got in (a). Hint: be sure to use aˆ = 1 and ˆb = 1.5 to do your coordinate transformation and to compute your controller, since you assume not to know the real values for control design purposes! At the same time, use the real a = −1 and b = 2 values in your simulation.
⦁ Instead of feedback linearization, you will now implement a sliding mode controller. The approach is to figure out what x2 should be if we considered it as an input to the x˙1 equation so that x1 is driven to zero. Design a linear manifold of the form s = cx1 +x2 that does the job by considering what happens when s = 0. Next, analyze the dynamics of s and determine a sliding mode controller that drives s to zero (and consequently x to zero).
⦁ Simulate your sliding mode design. Note that if you use the “sign” function in Matlab, ode45 will take a very long time to run. Instead, it is suggested that you use the approximation , where
if y ≥ 1
satif − 1 < y < 1
if y ≤ −1
Tune to understand the trade-off involved.
⦁ Sliding Mode Control for the van der Pol Equation The controlled van der Pol system is given by
x˙1 = x2

where and µ are positive constants, and u is the control input.
⦁ Pick values for and µ, and verify via simulation that for u = 1 the van der Pol system exhibits a stable limit cycle outside the surface , and that for u = −1 there exists an unstable limit cycle outside the same surface.
⦁ Define the sliding manifold , where r < 1/µ. Show analytically that if we restrict the motion of the system to the surface s = 0 (that is, we force s(t) ≡ 0), then the resulting behavior is that of the linear harmonic oscillator
x˙1 = x2 x˙2 = −ω2×1,
which exhibits a sinusoidal oscillation of frequency ω and amplitude r.
⦁ Design a sliding mode controller that drives all trajectories whose initial condition is withinthe region {x ∈ R2 : |x1| < 1/µ} to the manifold s = 0, and then has the states slide on that manifold towards the origin. Simulate your controller and verify that it is able to regulate the state to zero. Show your plots of x vs time and x2 vs x1 to demonstrate your design.
⦁ MIMO Control of a Two-Link Planar Arm
The robot arm in Figure 1 consists of two links. The first one mounted on a rigid base by means of a frictionless hinge and the second mounted at the end of link one. The joint axes z0 and z1 are normal to the page. We establish the base frame x0y0z0 as the work space frame, which means the arm moves within the x − y plane. The inputs to the system are always the torques τ1 and τ2 applied at the joints.

Figure 1: Two-link planar manipulator.
A dynamic model of this system can be derived using Lagrangian equations and is given by
,
where
H11 = I1 + I2 + m1lc21 + m2[l12 + lc22 + 2l1lc2 cos(θ2)],
H22 = I2 + m2lc22,
H12 = H21 = I2 + m2[lc22 + l1lc2 cos(θ2)], h = m2l1lc2 sin(θ2),
g1 = m1lc1g cos(θ1) + m2g[lc2 cos(θ1 + θ2) + l1 cos(θ1)], g2 = m2lc2g cos(θ1 + θ2).
In this project, we use the following parameter values: m1 = 1.0kg, mass of link one; m2 = 1.0kg, mass of link two; l1 = 1.0m, length of link one; l2 = 1.0m, length of link two; lc1 = 0.5m, distance from the joint of link one to its center of gravity; lc2g = 0.5m, distance from the joint of link two to its center of gravity; I1 = 0.2kgm2, lengthwise centroidal inertia of link one; I2 = 0.2kgm2, lengthwise centroidal inertia of link two; and g = 9.804m/s2, acceleration of gravity.
⦁ First, you will do joint space MIMO control of the arm, where the inputs are the two torquesand the outputs are the joint angles θ1 and θ2. Write a MIMO state space representation of the system dynamics. Then design the MIMO state feedback controllers (τ1 and τ2) for this system that regulate all the states to zero, and simulate the closed loop system for the initial conditions . Make sure you tune well the parameters of controllers, plot your controllers and all the states versus time, and provide an interpretation of your plot.
⦁ Second, we want to control the end-effector of the arm to generate a path in x − y plane. The outputs are the position coordinates x and y (z is always zero) of the end-effector. One way to approach this problem is to formulate the system directly into the end-effector coordinates. Let f : Q → R2 be a smooth and invertible mapping between the joint vector Θ = [θ1,θ2]> ∈ Q and the workspace variables X = [X0,Y0]> ∈ R2. The space Q is a suitably chosen range of angles for θ1 and θ2, and X = [X0,Y0]> is the position of the end-effector on the (x0 − y0) plane. In other words,
X = f(Θ),
so that the position of the end-effector can be computed from the two joint angles.
The mapping f is known as the arm’s forward kinematics, and it can lead us directly into so-called work space control, which you will perform instead of joint space control as done in part (a). There exists a relationship between the vector of linear velocities of the end-effector X˙ and the vector of velocities of joint variables Θ˙ , given by X˙ = JΘ˙ , where J is known as the Jacobian matrix.
Derive the forward kinematic function f : Q → R2 using trigonometry, and then show that the Jacobian is given by
.
Next, derive the new MIMO state space representation of the system dynamics, where now the state vector is X, instead of Θ. Design the MIMO state feedback controllers (τˆ1 and τˆ2) for this system that track the reference path below
,
and verify your design with a simulation for the initial conditions θ1(0) = 0, θ˙1(0) = 0, θ2(0) = 0.2, θ˙2(0) = 0. Plot your control signals and all the states versus time, and demonstrate an animation of the arm’s motion (use the example MATLAB code provided on Isidore).
(c) Finally, consider that normally the two-link arm has two configurations (i.e., elbow up and elbow down) for a particular non-singularity position of the end-effector. However, your closed-loop system always picks one solution from the two possible solutions. Why is this?
Warning: During your work space MIMO control, there exist some singularity positions when θ2 = kπ, where k = 0,±1,±2,···. The Jacobian matrix is not invertible and the controllers will be infinitely large at such positions. Please avoid these positions when you try to test your controllers!
General notes and hints:
⦁ The report to be turned in should be typed. I expect a professional-looking report, technically sound and easy to read.
⦁ Provide plots for all simulations that are requested. Make sure your plots are clear (do not use jpg files!), with relevant titles and axes labeled, and using a legend whenever several signals are plotted together. Any unclear or hard to read plot will cause you to lose points.
⦁ Keep your report succinct and to the point. Proofread it and spell check it. Poor English in your report will cause you to lose points.
⦁ Turn in your report via Isidore as a PDF file (no other format will be accepted), and upload your code uncompressed.

Technical Paper: Risk Assessment
Due Week 10 and worth 160 points

Global Finance, Inc. Network Diagram
Above is the Global Finance, Inc. (GFI) network diagram. A hypothetical company, GFI has grown rapidly this past year and implemented a number of network devices as displayed in the diagram. The company invested in the network and designed it to be fault tolerant and resilient from any network failures. However, although the company’s financial status has matured and its network has expanded at a rapid pace, its overall network security posture has not kept up with the company growth.

GFI’s network has historically been fairly stable, and the company has not experienced many full scale network outages. GFI has hired three (3) network engineers to keep up with the network growth, as well as the bandwidth demand by the company employees and the clients. However, the company has not hired any security personnel who can take care of the operational security responsibility.

The trusted computing base (TCB) internal network within the Global Finance, Inc. Network Diagram hosts the company’s mission critical systems that are vital to the company’s operations that also affect the overall financial situation. The Oracle database and email systems are among the most intensively used application servers in the company. GFI cannot afford system or network outages, as its cash flow and financial systems heavily depend on the network stability and availability. GFI has experienced DoS network attacks twice this year, and its Oracle database and email servers had been down for a total of one (1) week as a result. The recovery process required GFI to utilize $25,000 to restore its operations to the normal operating baseline. GFI estimated the loss from these network attacks at more than $1,000,000, as well as lost customer confidence.
Write an eight to ten (8-10) page formal risk assessment proposal in which you:
Describe the company network, interconnection, and communication environment.
Assess risk based on the GFI, Inc. network diagram scenario. Note: Your risk assessment should cover all the necessary details for your client, GFI Inc., to understand the risk factors of the organization and risk posture of the current environment. The company management will utilize this risk assessment to determine what actions to take; therefore, it must be comprehensive for the business leaders to make data-driven decisions.
Defend your assumptions where pertinent information from the scenario isn’t available.
Ascertain apparent security vulnerabilities, and analyze at least three (3) such vulnerabilities. Such analysis should entertain the possibility of faulty network design. Recommend mitigation processes and procedures for each of the identified vulnerabilities.
Justify your cryptography recommendations, based on security concerns and requirements, data-driven decision-making, and objective opinions.
Examine whether your risk assessment methodology is quantitative, qualitative, or a combination of these, and discuss the main reasons why you believe that the methodology that you utilized was the most appropriate.
Explain the way in which you would present your findings and assessment to the company’s management and thus facilitate security buy-in and concentration.
Using Microsoft Visio or its open source equivalent, redraw the CFI diagram, depicted as a secure and risk-mitigating model. Note: The graphically depicted solution is not included in the required page length.
Use at least three (3) quality resources in this assignment. Note: Wikipedia and similar Websites do not qualify as quality resources.
Your assignment must follow these formatting requirements:
Be typed, double spaced, using Times New Roman font (size 12), with one-inch margins on all sides; citations and references must follow APA or school-specific format. Check with your professor for any additional instructions.
Include a cover page containing the title of the assignment, the student’s name, the professor’s name, the course title, and the date. The cover page and the reference page are not included in the required assignment page length.
