摘要
深入分析了以定子电流、定子磁链为状态变量的异步电机状态观测器方案,提出了一种异步电机状态观测器的极点配置方法,系统地给出了这种观测器的设计过程。仿真研究表明,该方案对电机参数变化的鲁棒性好,磁链观测精度高,收敛速度快。基于该状态观测器方可实现高性能的无速度传感器运行。
The design approach of a full-order state observer for asynchronous motor, in which the state variables are stator current and stator flux linkage is presented, and the method of observer pole arrangement is proposed systematically. The simulation research shows that the observer gives very satisfactory estimation result of stator flux. With the proposed full-order observer, the flux linkage of motor can be achieved without shaft encoder.
