| 摘 要： | 根据永磁同步电机的数学模型,设计出一个滑模状态观测器,用于估算电机转子位置和速度并推导其状态方程,对其稳定性进行了分析。并且对此系统进行了Matlab仿真,仿真结果表明,该方法对电机参数变化不敏感,具有较强的鲁棒性。滑模变结构状态观测器能够在较广速度范围内追踪转子实际位置,实现对转轴位置的观测,从而实现了永磁同步电机的无传感器的控制。

| Abstract: | According to the mathematical model of the PM synchronous motor,a sliding model state observer was designed to estimate rotor′s position and speed,the state equation was derived and stability was analyzed.This system was simulated by Matlab and the results show that this method is not sensitive to parameter variation and has strong robustness.The sliding model state observer can track the real position of rotor in a large range of speed to realize the observation,thus the sensorless control for PM synchronous motor can be obtained. |
