基于Matlab永磁同步电机控制系统的仿真建模

在分析永磁同步电机(PMSM)数学模型的基础上，提出了PMSM控制系统仿真建模的新方法。在Matlab／Simulink中，建立独立的功能模块：PMSM本体模块、矢量控制模块、电流滞环控制模块、速度控制模块等，同时进行功能模块的有机整合，搭建PMSM控制系统的仿真模型。系统采用双闭环控制：速度环采用PI控制，电流环采用滞环电流控制。仿真结果证明了该方法的有效性，同时该模型也适用于验证其他控制算法的合理性，为实际电机控制系统的设计和调试提供了新的思路。

Modeling and Simulation of PMSM Control System Based on Matlab

Based on the mathematical model of the permanent-magnet synchronous-motor(PMSM), a novel method for modeling and simulation of PMSM system in Matlab had been proposed. In Matlab/Simulink, the independent functional blocks and such as PMSM block, vector controller block, hysteresis current controller block and speed controller, ect., had been modeled. By the organic combination of these blocks, the model of PMSM could be easily established. In the double loop of control system, a PI controller was adopted in the speed loop and a hysteresis current controller was adopted in the current loop. The reasonability and validity had been testified by the simulation results. The novel method offers a new platform for designing and debugging actual motors.
