Abstract
A motor controller configured to be coupled to a motor and to a system controller is described. The motor controller includes a proportional-integral (PI) regulator coupled to a timer controller. The motor controller is configured to generate, by the PI regulator, a pulsed signal representing a reported speed of the motor. Additionally, the motor controller is configured to transmit the pulsed signal to the system controller, measure a time period that elapses for the motor to make a predefined number of revolutions, measure a number of pulses transmitted in the pulsed signal, and determine a measured speed of the motor from the time period. Further, the motor controller is configured to determine, by the PI regulator, a difference between the reported speed and the measured speed, and adjust, by the PI regulator, the pulsed signal based on the difference between the reported speed and the measured speed.
