5. a) Consider the following system r(s); K y(s). s(s+1) 10s K Design K so that for an input r(t) there will be a 0.01 error in the steady state, where 100t, t0 r(t) = {0, otherwise 3/ b) Consider the following system r(s) K y(s) + s(s+30) Find the value of K that yields 20% overshoot for a unit step response.
