摘要:

根据永磁同步电动机的数学模型,设计了全阶状态观测器,直接得到反电动势的表达式。重点分析了全阶状态观测器系统的稳定性问题,推导出满足系统收敛性的反馈增益系数的取值范围。搭建了电机实验平台,进行了相关实验,实验结果验证了全阶状态观测器估算方法的可行性及其反馈增益系数取值范围的有效性。

Abstract:

The full-order state observer which can be observed the motor back electromagnetic force directly was designed based on the mathematical model of permanent magnet synchronous motor(PMSM) . The stability problem of the full-order state observer was analyzed in detail , and the range of the feedback gain coefficient which meet the system convergence was derived. The experimental platform of permanent magnet synchronous motor was built and some experiments were carried out to verify the feasibility of the method and the effectiveness of the feedback gain coefficient range.

Key words: permanent magnet synchronous motor (PMSM), sliding mode observer, full-order state observer
