1 1 vote A unity negative feedback closed loop system has a plant with the transfer function $\text{G}(s)=\frac{1}{s^{2}+2 s+2}$ and a controller $\text{G}_{c}(s)$ in the feedforward path. For a unit step input, the transfer function of the controller that gives minimum steady state error is $\text{G}_{c}(s)=\frac{s+1}{s+2}$ $\text{G}_{c}(s)=\frac{s+2}{s+1}$ $\text{G}_{c}(s)=\frac{(s+1)(s+4)}{(s+2)(s+3)}$ $\text{G}_{c}(s)=1+\frac{2}{s}+3 s$ Control Systems gate2010-ec control-systems transfer-function steady-state + – admin 213 views answer comment Share Follow Add Sync Questions Print 0 reply Please log in or register to add a comment.
