Question: Given figure shows three systems. System I is a positional servo system, System II is a positional servo system with PD control action, System

Given figure shows three systems. System I is a positional servo system, System II is a positional servo system with PD control action, System III is a positional servo system with velocity feedback. Calculate the unit-step and unit-ramp responses of the three systems as a function of time. Then compare their transient response characteristics, namely rise time, maximum overshoot and 5% settling time, and their steady state velocity error. Present your findings in a suitable table and comment. R(s) R(S) R(s) 5 5(1+0.8s) 5 System 1 1 s(5s + 1) System 2 0.8 System 3 1 s(5s + 1) 1 5s +1 C(s) C (s) 1 C3 (s)
