摘要
根据永磁同步电动机的数学模型及滑模变结构控制理论,设计了一个滑模状态观测器用于估算电机转子位置和速度,以dsPIC30F6010A DSP为核心构建了基于相电流采样的驱动控制系统。实验结果表明,所设计的滑模观测器能够准确估算电机转子位置,从而实现了永磁同步电动机的无传感器空间矢量控制。
A slide mode observer was designed to estimate the position and speed of the rotor according the mathemati- cal model of PMSMs and the theory of slide mode observers. A sensorless vector control system was established based on dsPIC30F6010A DSP by sampling phase current. The results show that the slide mode observer designed can precisely cal- culate the position of the rotor and accomplish the sensorless vector control of PMSMs.
