摘要：在介紹永磁同步發(fā)電機(PMSG)d，q軸數學模型和矢量控制理論基礎上，提出在直驅式永磁同步風
電系統機側采用PWM控制方式，通過轉子磁場定向控制策略．實現有功無功功率解耦控制，減小了損耗，并且
較好地控制了轉速。利用Matlab／Simulink進行仿真，并給出了仿真結果。同時搭建了基于TMS320F2808控制
器的試驗平臺，對該控制策略進行了實驗，實驗結果驗證了該控制系統的正確性與可行性。

Abstract；The PWM control strategy of directly—driven permanent magnet synchronous wind turbine sys—
tern in motor-side was presented，which based on the dq—axis mathematical model of PMSG and the vector con—
trol theory，by using the strategy of rotor field oriented，the active power and reactive power can be decoupled，
while the loss can be decreased，and the rotor speed is controlled very well．Matlab／Simulink was carried out
tO prove the validity of the system，and the simulating results was given．An experimental system based on
TMS320F2808 was set up to verify the validity and the feasibility．
Key words：directly-driven permanent magnet synchronous generators；vector control；rotor field oriented
