| 摘 要： | 针对直接转矩控制技术以容差形式的Bang-Bang控制模式给系统的稳态运行带来的转矩脉动大、电流谐波成分重、定子磁链轨迹畸变等问题,将非奇异终端滑模控制应用到了转矩和磁链控制中.为了提高传统滑模控制的收敛性,分别独立设计了转矩控制器和磁链控制器的非奇异终端滑模平面.转矩控制器和磁链控制器由等效控制项和非线性切换项组成,非线性切换项中的符号函数sgn(S)通过积分作用削弱了控制量的抖振.仿真结果表明,非奇异终端滑模变结构直接转矩控制具有动态响应快、转矩波动和转速波动小、鲁棒性强、低"抖振"的特点.

| Abstract: | For its inherent drawbacks of classic direct torque control(DTC),such as torque,flux linkage,and current ripples,a DTC scheme is presented,in which a terminal sliding mode variable structure control(TSMVSC) method is applied to electromagnetic torque and stator flux linkage control.In order to improve convergence performance of the conventional sliding mode variable structure control,the nonsingular terminal sliding mode surfaces of torque controller and flux linkage controller were independently designed.T... |
