摘要
为了研发一种可以取代传统有位置传感器的无传感器PMSM驱动控制系统,在分析滑模变结构控制理论(SMC)及永磁同步电机(PMSM)数学模型的基础上,建立起基于滑模观测器(SMO)的无传感PMSM矢量控制系统的数学模型,并搭建了采用id=0矢量控制策略的无传感PMSM矢量控制系统的仿真模型并进行仿真研究。结果表明,应用滑模观测器法可以准确估算出电机转子的位置,并能对电机电流和转速进行快速的跟踪,进而验证了滑模观测器应用在无传感PMSM驱动控制系统中的可行性与正确性。
In order to develop a sensorless PMSM driving and control system to replace the traditional position sensor,one sensorless PMSM vector control system mathematical model based on sliding mode observer（SMO）has been established by analyzing the theory of sliding mode control（SMC）and the mathematical model of permanent magnet synchronous motor（PMSM）,and has built the sensorless PMSM vector control system simulation model which adopted id=0 vector control strategy and analyzed the simulation results.The results show that the slide mode observer method can estimate rotor position accurately,it can trace the current and torque rapidly,the correctness and feasibility of SMO theory are verified which applied on PMSM drive and control system.
