　　摘要在介紹永磁同步發(fā)電機（PMSG）d，q軸數(shù)學(xué)模型和矢量控制理論基礎(chǔ)上，提出在直驅(qū)式永磁同步風(fēng)電系統(tǒng)機側(cè)采用PWM控制方式，通過轉(zhuǎn)子磁場定向控制策略．實現(xiàn)有功無功功率解耦控制，減小了損耗，并且較好地控制了轉(zhuǎn)速。利用Matlab／Simulink進行仿真，并給出了仿真結(jié)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(jié)果驗證了該控制系統(tǒng)的正確性與可行性。

　　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．
