| 摘 要： | 设计了具有变截止频率特性相位补偿及带有开关增益自适应率的滑模观测器,采用李亚普诺夫理论对其稳定性进行分析。理论上该方法对参数变化具有很强的鲁棒性,并且能够在较宽速度范围内追踪转子实际位置。在基于TMS320LF2808的永磁同步电机(Permanent Magnet Synchronous Motor,简称PMSM)的无传感器控制系统上进行验证,实验结果表明该系统具有良好的性能。

| Abstract: | This paper designs a slide-mode observer with variable cut-off frequency phase compensation and gain switch controller rules.The stability of system is analyzed by using Lyapunov theory.This method is robust to the different parameters of permanent magnet synchronous motor(PMSM),and it's able to track the real position of rotor in a wide range of speed.Using the sensorless control system of PMSM based on TMS320LF2808 as example,the experimental results prove that this system has good performance. |
