开关磁阻电机的模糊滑模控制策略研究

摘要

本文提出一种带有模糊滑模控制的开关磁阻电机转矩脉动抑制方案.针对SRM的非线性和时变性,设计了以电流偏差作为切换函数的滑模变结构控制器,并运用模糊规则对开关增益量进行智能控制,增强了系统准确性和稳定性.仿真结果表明此方案能够精确跟踪绕组电流,有效抑制转矩脉动,实现SRM电动机的高性能控制.%The paper presents a torque control strategy of switched reluctance motor, which has a fuzzy-sliding mode controller.For the nonlinear and time varying, the variable structure controller uses the current deviation as the switching function, in addition, fuzzy rules is applied to control the switch gain intelligently. Therefore, it enhances the accuracy and stability of the system. Detailed simulation results show that this scheme not only tracks winding current precisely but also reduces the moment's fluctuation significantly. It results in a high performance control of SRM torque.
