摘　　要：针对双馈发电机数学模型具有非线性、多变量、强耦合等特点,在矢量控制的基础上,提出了采用双闭环模糊PI控制方式,其中转子电流内环为PI控制,转子旋转角速度ωr外环为模糊PI控制,按照双馈发电机性能指标最佳控制中的功率因数最高控制方式,使用MATLAB对其建模并仿真,验证了所采用控制方法的正确性和可行性,并可实现在比较宽的风速范围内实现较大风能的吸收;当风速发生变动的工况下系统也具有良好的动态品质。According to that the mathematical model of doubly fed generator has the characteristics of nonlinear,multivariable,strong coupling and so on,on the basis of vector control,double-close-loop Fuzzy PI control is put forward,and an inner rotor current loop is by PI controller and an outer rotating angular velocity of rotor loop is by Fuzzy-PI controller.Uses MATLAB on the modeling and simulation to verify the correctness and feasibility of the control method,and now a wide range of wind speed to achieve the absorption of wind energy is relatively large;when the wind speed is occurred changes in operating conditions,the system also has good dynamic quality.
