Question

Please provide the MatLab Code with thier respected images.
Add comments to the code so i know what is going on.
Explain each step when solving the problem, so i can follow allong and understand.
Thank You.

DO ALL PARTS. A-H... Please !!!!

Now consider proportional control of the plant from Problem 1 (in the standard unity-feedback-configuration) a. For what gains K is the ciosed-loop system stable? b. As a function of the gain K, what is the steady-state error when tracking a unit-step reference signal? C. For gains K : 1, 5, 10, and 100, please nnd the gain margin, phase margin, and crossover frequency, and then find the rise time, overshoot, and steady-state rcference tracking crror of the control system d. If we wish to init the overshoot to 30%, what is the best achievable steady-state error? e. If we wish to limit the steady-state (unit-step) reference tracking error to 3%, what is the minimum achievable overshoot? What gain K achieves this minimum overshoot? What is the rise-time of the closed-loop system in this case? f. Let's say we use the gain found in part d. In this casc, what are the output and actuation signal of the closed-loop system when the reference signal is 1 + 0.01 cos(120 t)? g. Now let's say we instead use the PD controller K(1 +,, where K is the gain that you found in Part e. What are the steady-state tracking error, rise time, and overshoot of your design? h. When the PD controller from Part g is used, what are the output and actuation signal of the closed-loop system when the reference signal is 1 + 0.01 cos(120 t)?

And this is how it should be, using predefinided matlab functions:
