An actual rotation speed of the asynchronous motor is detected according to the given rotation speed thereof. A given voltage of the asynchronous motor is obtained according to a vector control algorithm and a PI-IP control algorithm and is used as a reference output voltage of the BBMC. A duty cycle of a power switch tube in the BBMC is obtained according to a finite-time control algorithm by taking capacitor voltages and inductor currents in the BBMC as control variables of the speed regulation system. The conducting time of the power switch tube in the BBMC is controlled according to the duty cycle and an output control signal of a corresponding switching cycle, so that an output voltage consistent with its reference output voltage is obtained at an output end of the BBMC, so that the actual rotation speed of the asynchronous motor accurately tracks the given speed.
