感应电动机效率优化的自抗扰控制研究

针对现有电动机效率优化控制方法存在控制算法复杂的问题,提出了一种基于改进自抗扰控制器的动态解耦控制策略。自抗扰控制器省去了微分跟踪器,采用线性的扩张状态观测器和线性状态误差反馈控制律,使控制算法得以简化。仿真和实验结果表明,该控制策略在保证电动机轻载运行时效率优化的同时,具有较强的抗干扰能力和鲁棒性,提高了效率优化过程中电动机转速的动态响应速度。

For problems of complex control algorithms of existing efficiency optimization control method of motor,an improved dynamic decoupling control strategy based on active disturbance rejection controller was proposed.The active disturbance rejection controller leave out differential tracker,and adopts linear expansion of state observer and linear state error feedback control law,so that the control algorithm can be simplified.The results of simulation and experiment show that the control strategy can ensure efficiency optimization of the motor under light loading operation,which has strong antiinterference ability and robustness,improves dynamic response speed of the motor in efficiency optimization process.
