摘要：
The present invention provides a motor controller for controlling a DC motor according to a reference signal. The motor controller includes a compensator, a pulse width modulation unit, and a motor driving unit. The compensator generates a control signal according to the reference signal and a sensing signal from the DC motor. The pulse width modulation unit generates a motor control signal by comparing the control signal and a ramp signal having a varying frequency. The motor driving unit receives the motor control signal and drives the DC motor according to the motor control signal.
