MOTOR CONTROLLER WITH AUTO GAIN TUNING FUNCTION AND CONTROL METHOD THEREOF

摘要

PURPOSE: A motor controller with an automatic gain compensation function and a control method thereof are provided to drive a motor precisely by controlling a gain value according to an operation mode selected by a user. CONSTITUTION: A motor(100) generates the rotation power. An encoder(110) detects the rotation value of the motor. A subtracter(120) subtracts the rotation value from the command value. A driving signal output unit(130) outputs the driving signal to the motor by controlling the gain of the output signal of the subtracter. A load amount detector(140) detects the load amount of the motor. A gain controller(150) outputs a gain value of an operation mode to the driving signal output unit according to the mode selection signal. A storage controller(160) constructs database of the command value, the gain value, the error value, and the load amount.
