永磁同步电动机预测函数控制的仿真研究

Simulation Study of Predictive Functional Control for PMSM

针对永磁同步电动机（PMSM）本身固有的强耦合、非线性、参数时变的特点以及传统控制方法对电动机数学模型依赖性强的缺点，在研究和分析预测函数控制算法的基础上，设计了预测函数控制与矢量控制相结合的永磁同步电动机交流伺服系统。通过仿真及与PI控制的结果对比表明．预测函数控制能够改善永磁同步电动机交流伺服系统的整体控制性能。

In view of the inherent strong coupling, nonlinear and time-varying parameters of PMSM as well as the shortcoming of the traditional control methods depend on accurate motor models parameters, on the basis of research and analysis of predictive functional control, the predictive functional control and vector control combination of AC PMSM servo-system has been designed. Comparison with the simulation results of PI control show that the predictive functional control can improves the overall performances of AC PMSM servo-system.
