Problem 3 (10 points): Steady-state error. Consider the feedback control system shown in the figure, where G(s)=s+24,H(s)=s+42. (a) If the equivalent unity feedback system can be expressed as T(s)=R(s)Y(s)=1+Z(s)Z(s), Find the expression Z(s). (b) Find the position, velocity, and acceleration error constants, Kp,Kv, and Ka, for nonunity feedback. (c) Find the steady-state error esS for R(s)=1/s (step), R(s)=1/s2 (ramp), and R(s)=1/s3 (acceleration/parabola). Answer: 0,1/8,∞.
