Question:

In order to reduce the steady-state error of the parabolic trough collector system, a PI controller is added to the open-loop transfer function so that (Camacho, 2012)

a. Draw the new resulting Nyquist diagram when K = 1.

b. Find the range of K for closed-loop stability.

c. Use a phase margin argument to find the value of K that will yield ζ = 0.5 damping factor.

d. Using the value found in Part a, simulate the system for a unit-step response using a computer program.
