Sample Questions from this Test

1. The loop-gain function L(s) of a control system with unity feedback is given to be $L\left(s\right)=\frac{k}{\left(s+1\right)\left(s+2\right)\left(s+3\right)}$, where k > 0. If the gain cross-over frequency of the loop-gain function is less than its phase cross-over frequency, the closed-loop system is
