摘　　要：传统直流电机运行效率高、调速性能好,但其固有的机械换向器和电刷导致电机容量有限、易产生火花、噪音大、可靠性差,直流无刷电机有传统直流电机优良的机械特性及控制特性,它的电枢绕组放在定子上,并在转子上安装永久磁钢,用电子换向器取代了电刷和机械换向器,解决了传统直流电机存在的弊端,直流无刷电动机具有结构简单、运行可靠、维护方便以及调速性能好等优点,因此是吸尘器用电动机的首选。采用防积分饱和PI调节算法,可消除积分饱和带来的不利影响,通过MATLAB中的Simulink工具箱对系统进行仿真,参考给定转速的速度响应曲线,系统的性能良好,控制策略可行。The traditional DC motor has the advantages of high efficiency, good speed performance and so on, but its inherent mechanical commutator and brush leads to limited motor capacity, sparks, noise and poor reliability. The rapid development of DC brushless motor with electronic commutator replace the brush and mechanical commutator to solve the drawbacks of the traditional DC motor, while maintain the advantages of a traditional DC motor well. Since the BLDCM（ brushless DC motor） has a simple structure, reliable operation, easy maintenance, good speed performance and many other advantages, it is the preferred motor for vacuum cleaner. The subject use anti-integral saturation PI adjustment algorithm to eliminate the negative impact brought by integral saturation, the control strategy is feasible and the system performance is good with reference velocity response curve of given speed through system simulation by MATLAB/ Simulink toolbox.
