[1] In Figure 1, consider the closed-loop system with measurement noise N(s), where G(s) = 100 s+100 G (s) = K?, H(s) = K? S+5 In the following analysis, the tracking error is defined to be E(s) = R(s) - Y(s): R(.s) G(s) G(s) Y(s) H(s) N(s) Figure 1 Rajah 1 a. Compute the transfer function T(s) = Y(s) / R(s) and determine the steady-state tracking error due to a unit step response, that is, let R(s) = 1/s and assume that N(s) = 0. (35 marks) b. Compute the transfer function Y(s)/N(s) and determine the steady-state tracking error due to a unit step disturbance response, that is, let N(s) = 1/ s and assume that R(s) = 0. Remember, in this case, the desired output is zero. (35 marks) c. If the goal is to track the input while rejecting the measurement noise (while minimizing the effect of N(s) on the output), how would you select the parameters K1 and K2? Why? (30 marks)
