PI-compensator C(s) G(s) Y(s) A system is defined by a transfer function G(s). SK+K i. Design a PI controller C(s)=- oft, = 0.5s. Hand solving S . s+1 H H(s) = 1 (unity feedback system) to have an overshoot less than 25% and settling time ii. Analyze and compare uncompensated and compensated responses.
