摘　　要：在分析无刷直流电机(BLDCM)数学模型的基础上,建立了控制系统的仿真模型,提出了一种新型的模糊PI智能控制方法。在BLDCM双闭环调速系统中,电流控制仍采用PI控制器,而转速控制通过采用常规PI控制和模糊控制相结合的方法来实现。结果表明,这种新型的模糊PI智能控制方法响应快、无超调、鲁棒性强、抗干扰能力好,较传统PI控制具有更好的动、静态特性。Based on the mathematical model of BLDCM, a novel fuzzy PI intelligent method is proposed for controlling the speed servo system. In the double loop of speed servo system, the conventional PI controller is implemented in the current loop, in the speed loop the fuzzy PI hybrid control scheme is applied. Several tests based on the minitype BLDCM are conducted to confirm the effectiveness of the proposed controller. Experimental results show the improved scheme has high dynamic and static performance and is superior to the traditional PI controller.
