摘　　要：给出了一个主电路为交-交变频器,采用定子磁场定向的矢量控制双馈调速系统,介绍了系统结构,给出了系统控制框图和控制部分主程序流程图,用Matlab/Simulink软件对整个系统作了仿真并得出仿真波形。该系统通过外围硬件电路完成对所需信号的检测,利用高性能的TMS320LF2407A型DSP芯片来实现控制系统中的复杂控制算法,大大提高了系统的控制精度,顺利实现了双馈调速系统中的矢量控制。A double-fed speed regulation system was provided, the system took an AC/AC cycloconvertor as main circuit,adopted the stator magnetic field orientation vector control. Its structure was introduced,its control block diagram and main program flow chart for control part were provided, simulated overall system by Matlab/Simulink and gave simulation waveform. This system detects signal through peripheral hardware cir- cuit,achieves complicated control algorithm by means of high-powered TMS320LF2407A chip, enhances control accuracy of the system greatly,realizes the vector control of double-fed speed regulation system successfully.
