Abstract
A vector control system of permanent magnet synchronous motor(PMSM) was introduced.A double closed-loop control system with current and speed loop was applied with TMS320F2812 as core of the system.The space vector pulse width modulation(SVPWM) was used in the control system.It stated the control system principle and introduced the hardware and the software program of the system.Finally,the whole control system was simulated under different test conditions.The simulation results proved that the system had many advantages such as the effec-tiveness of the control model,small speed overshoot,excellent antrinterference technique and rapid dynamic response and so on.
