Simulation Research of Vector Control System of Permanent Magnet Synchronous Motor

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.
