306SE Control systems Assignment, SUTD, Singapore: Determine the desired closed-loop poles in the s-domain based on the damping ratio and natural frequency

Question 1: Determine the desired closed-loop poles in the s-domain based on the damping ratio and natural frequency of the system that you have calculated in PART 1.

Use MATLAB to plot the root locus based on the motor transfer function)(GTP that you have obtained in PART A Q4 (without compensator)

Print the root locus with only the P-controller and with the PID controller (with
compensator) and comment on the difference between them. Write two different scripts/m-file for this and compare the two different results, and comment on its stability.

Question 2: Select the compensator zero to cancel one pole of)(zGHP {other than z=1}.
a = _______________

Question 3: Simulate your system and the results Followings are required for this part:
• Final system block diagram (use the Simulink block diagram)
• Simulation result (overview) from Simulink
• Enlarged simulation curve clearly shown the overshoot and settling time (Simulink)
• Complete m-file listing in this part C.

Question 4: derive the state space representation of the system with the new PID controller Use Matlab to acquire the state space representation for the new transfer function G(z) (using PID compensator)
Write a simple m-file code to apply the unit step and get the output result for this new transfer function and compare these results with your results in Part B (using only the P controller).
