In this paper, for achieving fast speed response and stabily statical characteristics in permanent magnet synchronous motor, a vector control system based on DSP is introduced. The vector control is embedded into the control systerm, and the mathematical mode and driving principle is given. The simulation and experiment result show this vector control syserm is highly dynamic, meeting the requirements of control system for hybrid electric vehicles, achieving the desired design goals, making the permanent magnet synchronous motor gets fast speed response and stabily statical characteristics
