摘要
新型风电机组传动系统的控制主要取决于液力机械部分的控制。由于风速具有非线性、时变不确定性,难以建立精确的数学模型,应用常规PID控制器不能达到理想的控制效果。提出应用参数自整定模糊PID控制器对液力机械部分进行控制仿真,首先根据风电机组传动系统特点,对风电传动系统建立数学模型,然后通过不同风速经由新型传动系统,得到发电机输入转速、功率、扭矩。实验表明,应用参数自整定模糊PID控制器能对风电传动系统进行较好的控制。
New wind turbine hydraulic drive system of control depends on the control of mechanical parts.As the wind speed is a nonlinear,time-varying uncertainty,it is difficult to establish a precise mathematical model.By using the conventional PID controller the desired control effect can＇t be achieved.So Parameter Self-turning fuzzy PID controller is proposed to control hydrodynamic transmission component.Firstly,according to transmission characteristic of the wind turbine,mathematical model for wind turbine＇s drive system is established;then various speed of wind is input to the model and the wind speed and torque and power of generator is attained.The experiment shows that parameter self-turning PID controller can better simulate and analyze the wind turbine＇s drive system.
