Marks: +1, -0

In a closed-loop system in which the output is the speed of a motor, the output rate control can be used to ____

Limit the speed of the motor
Limit the torque output of motor
Limit the acceleration of the motor
Reduce the damping of the system

Solution:

In a closed loop system in which the output is speed of a motor, the output rate control can be used to limit the acceleration of the motor.
Because rate of change of speed is acceleration.

[\acceleration (a)={dw}/{dt}]
