摘要
研究开关磁阻电机的非线性及转矩脉动是其较为突出的缺点。从滑模变结构的理论出发,通过将一类通用滑模变结构控制方法应用到开关磁阻电机的控制系统中。在开关磁阻电机精确模型未知情况下,利用滑模变结构控制的快速性和完全自适应性,实现对开关磁阻电机的有效控制。经仿真结果表明,方法能够有效降低开关磁阻电机的转矩脉动,并改善开关磁阻电机的动态性能,同时具有较强的鲁棒性。
Torque ripple and non - liner model are the major disadvantages of aswitched reluctance motor （ SRM ）. Based on the theory of Variable - Structure control with Sliding mode, a general design of sliding mode controller is pplied to the control system of SRM. Without knowing the precise model of motor the design of controller is realized and the process of design is also simplified, which makes use of its rapidity and fully self - adaptability. It is shown through the computer simulation experiments that , comparing with tradition control, the VSS improves system dynamic performance and robustness, and reduces motor torque ripple effectively.
