Unformatted text preview: A and the poles of the transfer function? 3. (34pts) Consider the system model depicted in Figure 2. (a) What is the system type of the process, G ( s )? (b) For each case below, design a controller to meet the stated steady-state tracking error speciﬁcations due to the disturbance, D ( s ): 1. The disturbance is a unit step. The desired steady-state error to the disturbance is zero. 2. The disturbance is a unit ramp. The desired steady-state error to the disturbance is less than 0.1. 3. The disturbance is unit ramp. The desired steady-state error to the disturbance is zero. R(s) +-Y(s) Process, G(s) Controller 2 s ( s +2) + D(s) + + N(s) G c (s) Figure 2: Block Diagram for Problem 3....
