摘要
在讨论永磁同步电机转子三种基本结构基础上,建立了永磁同步电动机在旋转坐标系下的数学模型。提出基于转子磁链定向的永磁同步电机转速、电流双闭环矢量控制策略,并在Matlab/Simulink环境下搭建系统模型,进行仿真验证。最后,构造以dSPACE1103为核心的永磁同步电动机实验平台,对一台1.5kW的面贴式永磁同步电动机进行了矢量控制变频调速研究。仿真和实验结果表明,基于矢量控制的永磁同步电机变频调速系统具有良好的动、静态性能。
Three basic structures of PMSM rotor is discussed firstly and then the mathematic model of PMSM is established in rotating coordinate system. Based on rotor flux orientation, the speed and current double closed loop vector control of PMSM is proposed. The Matlab/Simulink is used to build the system model for simulation. Finally, an experiment platform equipped with dSPACE1103 as the core is set up for speed regulation performance study in 1.5KW interior-type PMSM VC system. Simulation and experimental results show this vector control technology makes PMSM variable frequency drive system have good dynamic and static performance.
