9 Analytically Calculate The Steady State Error Due To The Disturbance And The Reference Signal What Can You Infer Fro 1 (539.82 KiB) Viewed 57 times
9) Analytically calculate the steady state error due to the disturbance and the reference signal. What can you infer from the values obtained? [7 marks] 10) Prove that the output y(t) will only track steady-state targets if there is an integrator in either a feedforward controller C(s) or the plant G(s). What other condition is required? In addition, using a mathematical derivation, specify the requirement for disturbance signals to be totally rejected, that is to have no steady- state impact on the output? [12 marks] 11) Use MATLAB to investigate how offset and performance varies as you change the scalar controller gain Kp. Give some generic conclusions based upon what you observe. [7 marks]
