Consider the system shown in Figure, determine characteristic equation. Hence find the following when excitation is a unit step 1.2 R(s) 20 C(s) s(s + 1) (0.2s + 1) S. 6. (a) overshoot (d) Settling time (e) Number of cycles before the response is settled within 2 % of the its final value. (f) Time interval after which maxima and minima will occur. Damped frequency of oscillation (b)Damping ratio and damping factor (c) Maximum
