Q2 The angular position c of a mass is controlled by a servo system through a referen
signal °r. The moment of inertia of moving parts referred to the load shaft, J, is 150 kebo
and damping torque coefficient referred to the load shafi(B, is 4.5 x 103 Nw-m fraden
The torque developed by the motor at the load s 7.2 x 10* Nw-m per radian of error
(a)Obtain the response of the system to a step input of 1 rad and determine the peak
time, peak overshoot and frequency of transient oscillations. Also find the steady
state error for à constant angular velocity of 1 revolution / minute.
(b)If a steady torque of 1000 Nwm is applied at the load shaft, determine the steady
Kan
state error.
