Question:

The open loop transfer function of a unity feedback system is $\mathrm{G}(s)=\frac{\mathrm{K}}{s(1+0.1 s)}$. If the steady state error of the system is specified to be limited to $1 \%$ on unit ramp excitation, determine the values of gain margin (GM), phase margin (PM), gain cross over frequency $\left(\omega_{g c}ight)$, phase cross over frequency $\left(\omega_{p c}ight)$, resonant frequency $\left(\omega_{r}ight)$ and resonant peak $\left(\mathrm{M}_{r}ight)$.
