Method for searching excitation signal of motor, and electronic device

A method for searching an excitation signal for a motor, comprising:

• step A of randomly generating M excitation signals for the motor, wherein M is a positive integer;
• step B of determining whether the M excitation signals satisfy a preset condition, wherein the preset condition is satisfied when any one of the M excitation signals allows a vibration sense obtained after the motor is driven by the one excitation signal to he an expected vibration sense;
• performing step C if the M excitation signals satisfy the preset condition, or performing step D if the M excitation signals do not satisfy the preset condition;
• step C of outputting an optimal excitation signal of the M excitation signals as an excitation signal output as a result of the searching, wherein the optimal excitation signal is the excitation signal that allows the vibration sense obtained after the motor is driven by the excitation signal to be the expected vibration sense;
• step D of calculating the M excitation signals according to a preset genetic algorithm to obtain a new generation of M excitation signals;
• and
• step E of determining whether the new generation of M excitation signals satisfy the preset condition;
• performing the step C if the new generation of M excitation signals satisfy the preset condition, or performing the step D if the new generation of M excitation signals do not satisfy the preset condition.
