Problems solved by technology

Generally speaking, during the vibration process of the motor, its characteristic parameters will change with the change of displacement, which we call nonlinear parameters, and this change will cause the actual vibration effect of the motor to be different from the expected effect when the signal is designed. , thus affecting the tactile experience

Abstract

The invention provides a motor signal compensation method. The motor signal compensation method comprises the following steps: acquiring an original signal and nonlinear parameters of a motor; calculating a compensation signal of the original signal according to the acquired motor non-linear parameter and a compensation formula; and transmitting the calculated compensation signal to the motor to excite the motor to vibrate. The invention further discloses electronic equipment and a storage medium. According to the motor signal compensation method, compensation processing is carried out on theoriginal signal by combining the nonlinear parameters, so that the actual vibration effect of the motor after the compensation signal is obtained is closer to the expected effect, and then the touch experience better meeting the expectation is obtained.

Description

【Technical field】 [0001] The invention relates to the technical field of motor detection, in particular to a motor signal compensation method, electronic equipment and a storage medium. 【Background technique】 [0002] The tactile feedback technology of the prior art is more and more widely used in daily life, including force feedback requirements of electronic products or other touch screens, etc., and people's requirements for the accuracy of vibration output effects are also getting higher and higher. As the carrier of this effect, the linear motor (that is, the linear resonant actuator, also referred to as LRA) is self-evident, and the requirements for its control accuracy are getting higher and higher. Generally speaking, during the vibration process of the motor, its characteristic parameters will change with the change of displacement, which we call nonlinear parameters, and this change will cause the actual vibration effect of the motor to be different from the expect...
