摘要： A method for compensating a signal of a motor includes acquiring an original signal and nonlinear parameters of the motor; calculating a compensation signal for the original signal according to the acquired nonlinear parameters; and loading the calculated compensation signal into the motor to excite the motor to vibrate. An electronic apparatus and a storage medium are also provided. In this method, the original excitation signal is compensated for nonlinearity according to the nonlinear motor parameters, and is then used for exciting the motor. Therefore, the actual vibration effect can be closer to the expected effect as designed, which can bring more desirable tactility experience.
