Design of Real-time Takagi-Sugeno Fuzzy Controller Based on Digital Signal Processor and Its Application in Brushless DC Motor Control

提出了一种简化模糊控制算法 ,它通过把系统的输入输出空间划分为一个完备的模糊模式集 ,且寻找与实时输入对应的模糊模式 ,对整个系统进行了简化 ;在此基础上 ,设计了以数字信号处理器 (DSP)为核心的模糊控制器 ;描述了其在直流无刷电机控制中的应用。实验结果表明 ,该模糊控制器具有实时性强、响应速度快。

The paper proposes a novel simplified algorithm for Takagi Sugno fuzzy model,which divides the system's input/output space into a complete fuzzy pattern set by use of fuzzy rules, and search out the dominant fuzzy pattern related to the real time input variables set such that the overall system is simplified.Based on the simplified Takagi Sugeno fuzzy model,the fuzzy controller is developed by using digital signal processor and applied in brushless direct current motor control system. The experiment results show that the proposed fuzzy controller has better performance in the rapid response, real time and accuracy.
