| 摘 要： | 针对无轴承异步电机(BLIM)的逆系统解耦控制性能受负载和参数变化影响的问题,在转子磁链定向逆系统解耦控制的基础上,采用自抗扰控制器(ADRC)替换经典的PID控制器,将BLIM模型中的交叉耦合项、本体参数变化和负载视为“扰动”,统一用ADRC的扩张状态观测器(ESO)估测,非线性状态误差反馈控制器(NLSEF)进行补偿。仿真结果表明:采用了ADRC,系统具有较好的动态解耦控制性能；同时,对电机参数和负载变化具有更好的鲁棒性。

| 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. |
