Beschreibung
Zusammenfassung:	The invention discloses a PWM generation method and circuit, a driver control method, a motor and a system, and the PWM generation method comprises the steps: obtaining an instruction signal used for representing the polarity of instruction current based on the polarity of the instruction current of each phase of the motor; based on the polarity of the difference value between the instruction current and the actual current of each phase of the motor, obtaining a comparison signal for representing the polarity of the difference value between the instruction current and the actual current of each phase of the motor; an upper tube drive signal and a lower tube drive signal are obtained based on the command signal and the comparison signal. According to the PWM generation method, the corresponding instruction signal is obtained through the polarity of the instruction current of each phase of the motor, the corresponding comparison signal is obtained through the polarity of the difference value between the instruc
