On the basis of the mathematical model of Permanent Magnet Synchronous Motor (PMSM),speed control system using the vector control theory is introduced in this paper. In Matlab6.5/Simulink,the isolated blocks, such as PMSM block, coordinate transformation block,three phase current source inverter controller block, PI modulation block etc are modeled. Then a double closed loop control system which consists of the inner current-loop and the outer speed-loop is constructed. The result of simulation testified the Vector Control theory is correct and realizable.
