Embodiment Construction

[0050] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0051] In order to solve the problem of poor tactile effect caused by the overtravel of the linear motor, it is necessary to avoid the phenomenon of overtravel of the linear motor.

[0052] Based on the above problems, in this embodiment, a linear motor overtravel control method is proposed. The implementation of the method may rely on a computer program that can run on a computer system based on the Von Neumann architecture.

[0053] Such as figure 1 As shown, t...

Abstract

The embodiment of the invention discloses a linear motor overtravel control method. The method comprises the following steps: acquiring a maximum target acceleration value of the linear motor; obtaining a time domain threshold of the linear motor, wherein the time domain threshold is the maximum acceleration when the linear motor does not have an overtravel phenomenon; when the maximum target acceleration value is greater than or equal to the time domain threshold, acquiring an excitation voltage corresponding to the time domain threshold; determining an adjustment range of a maximum input excitation voltage of the linear motor based on the excitation voltage; and controlling the maximum input excitation voltage to be within the adjustment range to drive the linear motor to vibrate, so that the overtravel phenomenon of the linear motor is avoided, the tactile feedback effect of the linear motor is improved, and the structural design efficiency is improved. In addition, the invention further provides a linear motor overtravel control device, computer equipment and a storage medium.

Description

【Technical field】 [0001] The invention relates to the technical field of linear motors, in particular to a linear motor overstroke control method, device, computer equipment and storage medium. 【Background technique】 [0002] At present, linear motors are widely used as a tactile feedback device with better user experience. However, the current linear motors have overtravel phenomenon. Taking the X-direction linear motor as an example, the overtravel phenomenon refers to the motor vibrator of the X-direction linear motor. When vibrating along the X direction, it will also generate strong vibration in different directions (Y direction, Z direction) at a specific frequency. In practical applications, the phenomenon of motor overtravel should be avoided as much as possible. The phenomenon of motor overtravel is externally manifested as shelling, that is, the motor vibrator hits the shell, which will not only greatly reduce the user experience, but frequent shelling will have a...
