Motor control method, device and equipment and computer readable storage medium

Abstract

The invention discloses a motor control method, device and equipment and a computer readable storage medium. The method comprises the following steps: sampling a target acceleration waveform to obtain first acceleration data; calculating first driving voltage data according to the first acceleration data, and calculating first displacement data according to the first driving voltage data; according to a displacement peak value allowed by hardware design of the motor, adjusting the first displacement data to obtain second displacement data, wherein the absolute value of a displacement value in the second displacement data is not larger than the displacement peak value; and calculating second driving voltage data according to the second displacement data, and driving the motor to vibrate based on the second driving voltage data. According to the invention, mechanical collision between the motor vibrator and the shell due to the fact that the driving displacement corresponding to the acceleration waveform exceeds the maximum displacement range allowed by the hardware design of the motor can be avoided, so that performance reduction or damage of the motor can be avoided, and normal vibration of the motor is ensured.

Description

technical field [0001] The present invention relates to the technical field of motors, in particular to a motor control method, device, equipment and computer-readable storage medium. Background technique [0002] The application of motors in electronic equipment products is becoming more and more popular. For example, Linear Resonant Actuator (LRA) has been widely used in various vibration occasions of consumer electronics due to its advantages of strong vibration, richness, crispness, and low energy consumption. Especially games and AR / VR products. By constructing a variety of broadband vibration waveforms (acceleration waveforms), the motor can achieve very rich and realistic vibration feedback. However, when game developers construct vibration waveforms, since they do not accurately know the specific physical characteristics and control algorithms of the motor, it is difficult to ensure that the vibrator displacement corresponding to the vibration waveform is always wit...
