说明:
简述了模糊控制的基本原理及基于模糊自整定的无刷直流电机控制系统的设计。针对传统PID控制存在的不足,借助高端数字信号处理器TMS320F2812,将模糊自整定控制与BLDCM控制系统有效的结合在一起,控制系统的性能得到了较大改善,性能指标明显优于传统PID控制,进而增强了无刷直流电机运行的稳定性。
Study of BLDCM Control System Based on Fuzzy Self-tuning Control
Abstract: In this paper, given a presentation of the principle of the fuzzy control and the design of BLDCM control system based fuzzy self-tuning control. To handle the shortages of conventional PID control, recur to the TMS320F2812, digital signal processing, and combine the fuzzy self-tuning control with BLDCM control system. The results show the performances of control system are improved comparing to the conventional PID control, the performance index is better than that in conventional PID control system, so the stability of BLDCM operation is strengthened.
