摘　　要：将模糊控制用于双馈发电机,根据其磁场定向矢量变换控制特点,得出交流励磁变速恒频控制方法。在基于TMS320LF2812的双馈发电机系统实验平台上,使用C语言编写模糊控制器程序,在有功功率控制环节中以转速偏差和转速偏差变化率作为模糊控制器输入量,转子电流分量作为输出量。根据实验调试,合理选取论域及语言变量值,确定模糊控制规则,进行模糊推理计算,得到模糊控制器输出的精确值。在此基础上,进行了双馈发电机变速恒频控制实验,实验结果表明了模糊控制器设计的正确性。Fuzzy-control was used on the doubly-fed induction generator and according to the field-oriented vector transformation control technique, the AC-Excited Variable-speed Constant-Frequency controlling method was obtained. On the system experimental panel of the Doubly-fed Induction Generator system based on TMS320LF2812, the C language was used to program the fuzzy-controller. In the active control system, the fuzzy-controller make the speed error and its change as the input, the component of rotor current as the output, and the field and the language variable were chose reasonably, the fuzzy-control rule is established. The precise output result of fuzzy-controller was gotten by inference. On the base, the experiment for the variable-speed constant-frequency of Doubly-fed Induction Generator was conducted. The experimental results indicate that controlling method is correct.
