无轴承异步电机的自抗扰控制策略
Active Disturbance Rejection Control Strategy of Bearingless Induction Motor
摘要
Abstract
Focusing on the decoupling control performance of the bearingless induction motor (BLIM) inverse system was decreased,which was caused by the parameters variation and varying load.Based on the RFOC inverse system decoupling control strategy,active disturbances rejection control (ADRC) was designed to replace the traditional PID controller.In the control scheme,the cross coupling items and the change of motor parameters and load in bearingless induction motor system were regarded as disturbance.An extended state observer (ESO) was used for estimation,and nonlinear state error feedback (NLSEF) controller was applied to compensate disturbance.The simulation results obtained with ADRC showed that the system had excellent dynamic decoupling performance and strong robustness to the change of motor parameters and load.关键词
