Abstract
In this paper,based on the mathematical model of the permanent-magnet sychronous-motor(PMSM),a new way of PMSM vector control system model has been taken on.In matlab6.5/simlink,the isolated functional blocks,such as speed controller block,vector controller block,coordinate transform block,SPWM block etc.has been modeled.There are some blocks such as PMSM block,voltage inverter block which are provided by matlab6.5/simlink.By the organic combination of these blocks,a double loop of control system,the speed loop and a current loop are established.The validity has been testified by the simulation results and other control strategies can be applied to the system to testify their rationality.This novel method offers a new thought way for PMSM control system designing and debugging in actual application.
