摘　　要：风力发电系统已成为可再生能源利用中必不可少的一部分,它具有多变量、非线性以及不确定等特点,其变桨距功率调节技术逐渐成为主流技术。PID控制技术虽然能满足一般控制要求,但控制效果不很理想。在变桨距功率控制的基础上应用模糊PID控制,其中模糊PID控制器采用二维线性规则库和标准三角型隶属度函数的结构,通过MATLAB/Simulink仿真平台,验证模糊PID控制的合理性和优越性。The wind power system is absolutely necessary in renewable energy. It has multivariable, strong nonlonear and other characteristics. The variable-pitch power regulation control has been the mainstream technology. PID control effect is not satisfying. Adding fuzzy PID control into the variable-pitch power regulation control. Fuzzy PID controller includes two-dimensional liner rule base and triangle membership function achieves good performance. At last the fuzzy PID con- trol is verified for its rationality from MATLAB/SimuIink when errors exist.
