Simulation Research of Vector Control System of Permanent Magnet Synchronous Motor

分析了电压空间矢量脉宽调制原理和算法,建立了一种基于SVPWM的永磁同步电动机矢量控制系统的仿真模型,给出了各子模块的具体设计方案;对积分斜率法产生三角波的方法进行了改进。仿真和实验结果证明了所建模型的正确性和系统的可行性,为分析和设计PMSM控制系统提供了有效的手段和工具。

The paper analyzed the principle and algorithm of SVPWM,built a simulation model of vector control system of PMSM based on SVPWM,and gave concrete design scheme of each sub-module of the model.It also modified integral-slop method for producing triangle carrier.The simulation and experimental results showed that the model was correct and the system was feasible,which offers a valid mean and tool for analyzing and designing a control system of PMSM.
