摘　　要：永磁同步电机常规控制方法不能满足高稳定性和精确性控制要求。本文将精确线性化控制技术引入永磁同步电机控制研究中,利用微分几何原理推导出三相永磁同步电机系统满足线性化的条件,从而得到对应的状态反馈精确线性化模型和输入输出表达式。结合此模型,利用状态反馈,实现对电机转速的控制。MATLAB仿真验证了永磁同步电机精确线性化控制技术理论分析,并证明了其能够实现永磁同步电机系统的输入与输出线性化解耦控制。The conventional control of the permanent magnet synchronous motor(PMSM)is not able to realize the high precision and stability.In this paper,the precise linearization control technology being used for PMSM is introduced.The necessary conditions for linearization of the three-phase PMSM system is deduced by using differential geometry principle.The corresponding precise linearization model of state feedback and the expressions of input and output are obtained.Then,combined with this model,the motor is controlled on its speed by using state feedback.Finally,the MATLAB simulation results are present,verifying the effectiveness of the precise linearization control technology for PMSM,and it is concluded that the input and output linearization decoupling control of PMSM system is available.
