Abstract

A method for searching an excitation signal for a motor and an electronic device. The method includes: randomly generating M excitation signals for the motor, and determining whether the M excitation signals allow vibration sense obtained after the motor is driven to be expected vibration sense; if yes, outputting this excitation signal as an optimal excitation signal; if no, calculating the M excitation signals according to a preset genetic algorithm to obtain a new generation of M excitation signals, and then determining whether the new generation of M excitation signals allow vibration sense obtained after the motor is driven to be the expected vibration sense, until the optimal excitation signal is obtained. In the present disclosure, the optimal excitation signal for obtaining the expected vibration sense after the motor is driven can be quickly found, and thus an efficiency thereof is high.
