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 \(\left(\mathrm{M}_{r}ight)\).
