摘要
本文首次将受生物启发的分流模型引入开关磁阻电动机的变结构滑模控制,提出一种开关磁阻电动机的受生物启发滑模控制,以有效抑制其转速波动,提高其控制性能。仿真结果表明:开关磁阻电动机采用受生物启发滑模控制,其转速对给定转速的跟踪性能及负载突变时的性能比一般滑模控制更平稳、更准确;当系统参数变化时,受生物启发滑模控制器保持一般滑模控制器的鲁棒性。
As ideal sliding motion can't be formed in a practical system using sliding mode control,switched reluctance motors using sliding mode control still have the problem of large speed ripples.In this paper,a biological inspired shunting model is incorporated into the variable structure sliding mode control of a switched reluctance motor in order to improve its performances.The simulation results show that the speed tracking performance of the switched reluctance motor using the proposed biological inspired sliding mode control is stable and more precise than that using the conventional sliding mode control.In addition,the switched reluctance motor controller keeps the features of parameter insensitivity and rapid recovery from load disturbances.
