Designing a Lag Compensator (Problem no 1)

The forward path transfer function of a certain unity feedback control system is given by K G(S) = ________________ S (S+2) (S+8) Design a suitable lag Compensator do that the system meets the following specifications (i) Percentage overshoot is less than or equal to 16% for unit step input (ii) Steady state error is less than or equal to 0.125 for unit ramp input Root Locus design:    • Root Locus approach to control systems design   Ramp signal    • Ramp signal
