Control Systems

Consider a feedback control system under proportional control with forward and feedback transfer functions given by (Please refer to the attached file). (i) Use the Routh criterion to determine the range of positive proportional controller gain... (see attachment)

Block diagram in feedback control system form.

I attached a Word document with a circuit to analyze for: a) Draw a block diagram of the circuit in feedback control system form. b) Derive an expression for Io in terms of Vi and the system parameters Av, Ro, RL, and Rf. c) How should the system be designed to make Io independent of RL? What is the approximate expression for Io in terms of Vi? RL being load resistor.
