基于SMO的矿用永磁同步电机控制系统

Research on Mine Permanent Magnet Synchronous Motor Control System Based on SMO

为解决现有永磁同步电机(PMSM)控制系统体积大、设计成本高、系统可靠性低等问题,基于滑模观测器(SMO)原理,研究一种煤矿PMSM多参数精准控制方法,构建了PMSM控制系统模型,并利用MATLAB软件进行了仿真分析。结果表明,基于SMO变结构控制方法,可以在指定的范围内快速地追踪转子所在的具体位置,从而保证PMSM无传感器磁场定向控制水平。

In order to solve the problems of large volume,high design cost,and low system reliability of existing permanent magnet synchronous motor(PMSM)control system,based on the principle of sliding mode observer(SMO),a multi parameter accurate control method for coal mine PMSM was studied.A PMSM control system model was constructed,and simulation analysis was carried out using MATLAB software.The results show that based on the SMO variable structure control method,it is possible to quickly track the specific position of the rotor within a specified range,ensuring the sensorless magnetic field orientation control level of PMSM.
