DTC Variable structure fuzzy control of induction motor on electric vehicle
摘要
Abstract
Poor peed adaptive performance and low speed torque ripple were the common problems of Traditional direct torque control driving system of induction motor on Electric vehicle. A kind of induction motor direct torque drive control system based on speed, flux and torque variable structure fuzzy control method was put forward. The speed fuzzy adaptive PI control was used to ensure speed control stability of electric vehicle under variable load, and the flux and torque variable structure fuzzy control was utilized to solve the problem of torque ripple. The simulation and experimental results show that the system flux and torque are control ed more precisely, thus torque ripple in low speed is reduced, and speed fuzzy control makes electric vehicle get better driven adaptive control performance.关键词
