Q1. Consider the unity feedback control system with a PI controller shown below: a) Determine the closed-loop transfer function and the characteristic equation of this system. b) Determine the range of k for which the closed-loop control system is stable. c) Let k = l. Compute the steady-state error ess for a unit-ramp input, U(s). d) How would you modify the PI controller to get ess = 0? Justify your answer.

PID controller design using Root Locus: It is desired to design a practical PID controller (ideal derivative is multiplied by a low pass filter) using Root Locus technique. The structure of the controller is given by K(s) = KP + KDs + KI/s. The controller should satisfy the following design specifications/constraints: a. Transient response specifications: It is desired that the response of the closed-loop system, T(s), should exhibit the following properties when R(s) = 2/s and D(s) = 0: i. %OS < 15 (OVERSHOOT) ii. Ts < 100s (settling time) b. Constraint on the control input: The output of the controller should be bounded: |u(t)| ≤ 3V. c. Steady-state response specifications: There should be zero steady-state error for R(s) = 2/s and D(s) = 1/(5s) (Also prove analytically).
