A servo system excited with step response has a forward path function G(s) =K / S (S+1) with a negative feedback path H(s) =1+K2S. Analyze the values of K and K2 so that the maximum overshoot in the unit step response is 0.2 and the peak time is 1 sec. Justify the values of K and K2 affecting the rise time and settling time for tolerance band of 2% of steady state condition.
