Motor control system and method based on current feedback signal

Abstract

The present disclosure relates to a motor control system and method based on current feedback signal. The motor control system includes a control apparatus, a linear motor, and a current feedback apparatus, where an output end of the control apparatus is connected to the linear motor for calculating a displacement error of a previous moment to obtain a control output value of a current moment, and converting the control output value into a voltage signal for transmission to the linear motor; the linear motor is configured to vibrate according to the voltage signal input by the control apparatus; and the current feedback apparatus is connected to the linear motor, and is configured to: convert a measured current value of the linear motor into an actual displacement value of the current moment, and feed back the actual displacement value to an input end of the control apparatus.
