Unformatted text preview: Page 4 Problem 3 : Figure below shows the block diagram of the antenna control system of the solar-collector field. The signal ) ( s N denotes the wind dust disturbance acted upon the antenna. The feedforward transfer function ) ( s G d is used to eliminate the effect of ) ( s N on the output ) ( s Y . Find the transfer function ) ( / ) ( = R s N s Y . Determine the expression of ) ( s G d so that the effect of ) ( s N is entirely eliminated. Page 5 Problem 4 : Considering the feedback control system shown below, determine the feedback coefficients ( k 1 and k 2 ) so that the poles of the closed-loop control system are located at -5 and -7.
