The invention relates to a traction control system control method and device, a controller and a storage medium. The method comprises the steps that in the acceleration process of a target vehicle, a motor rotating speed signal, a motor output signal and the vehicle speed of the target vehicle in the current control period are obtained; obtaining harmonic frequencies and harmonic energy of a plurality of harmonic waves corresponding to the motor rotating speed signal, obtaining a harmonic energy ratio of each harmonic wave according to each harmonic energy, and obtaining a target harmonic wave from the plurality of harmonic waves based on the harmonic energy ratio; under the condition that the harmonic energy proportion or the vehicle speed meets a preset condition, a motor output control gain coefficient is obtained according to the harmonic energy proportion, the vehicle speed and the target harmonic frequency; generating a motor output instruction based on the motor output control gain coefficient and the motor output signal; the motor output instruction is used for controlling motor output of the traction control system of the target vehicle in the current control period. By adopting the method, the acceleration performance and the control stability can be improved.
