感应电机DTC模糊逻辑细分电压空间矢量控制
Fuzzy logic space voltage vector subdivision for induction motor DTC
摘要
Abstract
An induction motor DTC scheme based on fuzzy logic vector subdivision was proposed.Aiming to reduce the torque ripple and improve the control performance of flux and torque in DTC system,the flux error,torque error and flux angle segments were subdivided,the fuzzy logic theory was adopted to carry out the reasonable fuzzy classification,and then a fuzzy switch table was established by combining the subdivided twelve space vectors for the benefit of selecting the optimal space voltage to improve the stationary of flux and torque and to reduce torque ripple.The simulation and experiment results show that DTC performance of flux and torque based on fuzzy logic twelve space vectors is greater than traditional DTC.关键词
