The differential equation of a cruise control system is provided by the following equation:
Find the closed loop transfer function with respect to the reference velocity (vr) .
a. Find the poles of the closed loop transfer function for different values of K. How does the poles move as you change K?
b. Find the step response for different values of K and plot in MATLAB. What can you observe?
c. For the given transfer function, find tp, ts, tr, Mp . Plot the resulting step response. G(s) = 40/(s^2 + 4s + 40)
