基于模糊PI矢量控制的异步电机调速系统
Induction Motor Speed Control System Based on Fuzzy PI Vector Control
摘要
Abstract
On account of the characteristics of the induction motor(IM),which often suffer from unknown load variation and a wide speed range,instead of fixed-gain PI controller,a speed control scheme using fuzzy-logic control to adjust parameters of PI controller was presented. Moreover,the irregular triangles as the membership function which increases the number of rules around the zero error was used to improve the stability and steady precision of the system. Meanwhile,the back-to-back connected converters,achieving bidirectional energy flow,were applied in IM control system to enable DC voltage to be stable. Experimental results demonstrate that the performance of the proposed IM control system improve the dynamic and static performance and is more robust to load disturbances compared to the conventional PI controller.关键词
