摘要
从无刷直流电动机驱动器结构出发,提出了一种控制其转速的新方法。即利用滑模变结构控制的方法直接控制逆变桥功率开关管的通断,产生PWM波,达到控制其转速的目的。从抑制起动电流的角度出发,在原变结构控制方法的基础上给出了一种双环控制方法。利用仿真对所提出的方法进行了验证。
Based on the driving structure of brushless DC motor, a new method to control its speed was proposed in this paper, the switching state of the MOSFET was controlled by sliding mode control, producing PWM wave to control the speed of the BLDCM, from the viewpoint of restraining starting-current, on the basis of the sliding mode control, a double-loop control method was added and the above mentioned methods were validated by simulation.
