Part 2: Simulink Model for Analysis of closed-loop control System a) The motor transfer function is shown in Figure 2(a) and studies the performance of the system using Simulink if the input is a unit step signal. Choose your group number as a value of K₁: i) R(s) Determine the poles and the zeros of the system and discuss its stability. Also, plot the pole-zero map. ii) obtain the step response of the system, % overshoot, steady state error, peak time Tp and settling time Ts if possible. E(s) K₁ (a) Figure 2 Motor 25 s(s+1) C(s)

Control system, can you explain two differences between feedfoward and feedback for this figure ?

Need help only with parts D and E and no matlab help required, just computation

QUESTION 3 Consider a unity negative feedback control system. Assume that the plant G(s) does not have an integrator and you are using a proportional compensator K. You want to increase the closed-loop step tracking performance. Currently, the steady- state tracking error of the closed-loop system with K=K_old to a unit step signal is 0.1. You would like this error to be reduced to 0.02 with a new proportional compensator K=K_new. How does the proportional gain have to change to make this possible? We assume that the closed-loop is stable for all values of the proportional gain. Do not guess as incorrect answers will incur a penalty. K_new = 6.33 K_old K_new = 5.44 K_old K_new = 5 K_old K_new = 4.66 K_old
