| 摘 要： | 为了开发一种成本低、可靠性好、维护简单的无位置和速度传感器的控制方法,在分析永磁同步电动机PMSM的数学模型和滑模变结构控制基本理论的基础上,建立了基于滑模观测器SMO的PMSM无传感器驱动控制系统模型.以TMS320LF2407A DSP为核心构建了PMSM无传感器驱动控制系统,并进行了仿真和实验研究.结果表明,所提出滑模观测器能够准确地估算出电机的位置信息,并且系统具有较好的静、动态特性,从而验证了滑模观测器在无位置传感器PMSM驱动控制系统中应用的可行性和正确性.

| Abstract: | A low cost,high reliability position and speed sensorless control scheme is proposed in the paper.The paper has designed the sensorless controlling system of PMSM(permanent magnet synchronous motor) based on SMO(sliding mode observer) by analyzing the model of PMSM and the theory of SMO.The system is tested and verified on the experimental platform of sensorless PMSM system based on TMS320LF2407A DSP.The results show that the approach has better performance in position estimation and the system has better performance both in static and dynamic,thereby verified the correctness and availableness of the approach. |
