| 摘 要： | 提出了一种基于观测器理论的永磁同步电机无传感器控制方法。文中转子位置通过对磁通的估计而获得，速度反馈信息则通过一个闭环状态观测器进行估计，整个控制策略由一片ＤＳＰ３２０Ｃ２５执行，通过一台２５ｋＷ的电机测试表明，该方法在稳态、暂态条件下均能获得较好的结果。

| Abstract: | This paper presents a position and velocity sensorless control algorithm based on observer theory. Rotor position can be attained by flux linkage and line current estimation. A closed-loop state observer is implemented to compute the speed feedback signal. The control is realized by software using TMS DSP320C25.Experiment results on an SPM are reliable in both steady and transient states. |
