DC SYSTEMS AND METHODS FOR CALCULATING MOTOR POSITION INERTIA AND REST POSITION IN SENSORLESS BRUSHED DC MOTOR CONTROL SYSTEMS

摘要

The system according to the invention comprises a motor driver module and a motor positioning module. The motor driver module is configured to measure a current supplied to the motor. Wherein the motor positioning module is configured to determine whether the motor is in a first state when the power supply to the motor is initially stopped based on ripples of current supplied to the motor during a first period of time before the first time, 1 position. Wherein the motor positioning module is configured to determine the position of the motor at a second time after the power supply to the motor is stopped based on the first position of the motor at the first time and the rotation speed of the motor, 2 position.
