Question 3 (20 marks) The transfer function of a plant is represented by 10 G(S)(100s+1)(0.2s +1) = The Bode plot is shown in Figure 7. (4 marks) a) Estimate the phase margin b) If a compensator, Ge(s) 501 is to be used to control G(s), draw the new (S+0.8) (10 marks) asymptotic magnitude and phase Bode plots. c) Determine if the following design specifications are met with the use of the compensator Ge(s) in (b): the phase margin must not be less than 70° and the static position error constant, Kp 10 (6 marks) Bode Diagam Frency ) Figure 7
