Abstract: Disclosed is a swinging drive control apparatus, including a controller and a motor, where the controller detects a counter-electromotive force of the motor and drives the motor according to the detection result. Also disclosed is a corresponding method, including: measuring a counter-electromotive force of a motor in a previous cycle; and comparing a maximum counter-electromotive force value with a preset value, and calculating a PWM pulse duty factor in a next cycle. By directly detecting the counter-electromotive force of the motor without using a sensor, the present invention implements swinging frequency and phase tracking as well as swinging amplitude control, and simplifies a control system.
