Question:

A process, including the sensor and control valve, can be modeled by the transfer function:

4e-3s G(s) =

(a) If a proportional-only controller is used, what is the maximum value of controller gain K_c that will result in a stable closed-loop system? (Determine the exact value of K_c, not an approximate value.)
(b) Specify a PI controller using the AMIGO controller settings.
