For the closed loop control system of a scanning mirror with an angular velocity drive,
input,U1, to summer, to C [ (10(s+30)/(s(s+300) ], out in Volts to A [ 300 ] out in rad/s to P [ (640000}/(s^2+160s+640000) ] output to U2, with pickoff in rad/s to H [ 0.01 ] out in volts back to summer.
(a) find the loop transfer function and the input-output transfer function. Does the Nichols diagram enter the "6 db" line on Nichols diagram.
(b) Plot output time response for 1v step command. Plot output time response to a step disturbance of -.1 rad/s applied to the input of the plant.
