摘　　要：在分析DSP的无刷直流电动机控制系统的基础上,提出了模糊PI的控制算法,说明了DSP的控制系统硬件电路组成。在CCS开发环境下,基于TMS320F2812 DSP用C语言编程实现了模糊PI的控制算法,阐述了隶属度计算、模糊规则的实现和解模糊化的方法。运行结果表明模糊PI控制算法有较高的控制精度,实现了该控制系统的数字化。The fuzzy PI control algorithm was put forward and the hardware circuit structure of control system was illus- trated based on the analysis of DSP brushless DC motor （BLDC） control system. The fuzzy PI control algorithm based on TMS320F2812 was achieved by C language ＇programming under the CCS development environment, and the membership calculation, the realization of the fuzzy rules and the method of ambiguity resolution were described. The results show that the fuzzy PI control algorithm has high control accuracy and can realize the digitization of the control system.
