基于DSP的无刷直流电机P-模糊自适应PID控制系统

P-fuzzy Self-adaptive PID Control System for BLDCM Based on DSP

针对传统的速度、电流双闭环控制系统不能随外界变化而调整PID参数并且控制精度不高的问题,提出一种新型的P-模糊自适应PID控制方法且采用TMS320LF2407ADSP作为处理器。实验结果表明:该模糊控制系统运行平稳,具有较高的控制精度和较好的鲁棒性,实现了P-模糊自适应PID控制系统的数字化。

Against the fact that the traditional speed and current double closed-loop PID system was not able to adjust the parameter itself with rather low control accuracy,a novel p-fuzzy self-adaptive PID intelligent method was introduced,in which the TMS320LF2407 DPS was used as the processor.The experiment result showed that the fuzzy-control system operating stably with high precision and good robustness,to realize the entire digitalization of this p-fuzzy self-adaptive PID control system.
