Vector Control of Permanent Magnet Synchronous Motor Based on Sliding Mode Observer
根据滑模变结构控制理论,构造了滑模观测器,实现了永磁同步电机无位置传感器矢量控制.针对滑模变结构控制所固有的抖振问题,采用边界层法,有效抑制了抖振问题,提高了转子位置估算精度.通过仿真和试验,验证了所实现的改进滑模观测器的有效性.
To solve the problem of sensorless vector control of permanent magnet synchronous motor( PMSM ), a sliding mode observer was constructed and the continuous position was obtained by means of the sliding mode control theory. The boundary layer was used to solve the problem of the chattering in the sliding mode observer. Finally, the effectiveness of the sliding mode observer improved was proved by the simulation and experimental.
