摘　　要：本文将模糊控制的快速性与PI调节的静态无差相结合,提出一种基于矢量控制的模糊逻辑与PI结合的复合型控制器,同时设计了推力补偿器对动态纵向边端效应引起的推力的衰减进行了补偿.通过与PI调节的矢量控制系统的数值仿真结果的对比,验证了该复合模糊PI调节器对矢量控制下直线感应电机(LIM)动态性能的改善.To make use of the fast response of the fuzzy logic control（FLC） and the nullity of steady-state error of the PI regulator, we introduce a combination of proportional-integral（PI） regulator and fuzzy logical control（FLPI）. Meanwhile, we design a thrust compensator for compensating the reduction of thrust due to the longitudinal end-effect. A numeric simulation of the FLPI regulator is performed. Its effectiveness is verified by comparing the simulation results with those of PI regulated vector control of linear induction motor（LIM）.
