摘要
建立了变速变桨距风力发电机组的简化模型。在此基础上,将变论域自适应模糊控制应用到风力发电机组的转速和桨距控制系统中,改善风力发电机组的风能捕获性能。变论域自适应模糊控制器在保持规则形式不变的前提下,论域随着误差的变化而变化。这种控制器不但具有经典模糊控制的优点,如不需要精确的数学模型,产生非线性控制动作,良好的动态性能等,而且具有较高的控制精度。仿真结果证明该方法改善了风力发电机组的控制性能。
?A simplified model of variable speed variable pitch wind turbine is established. On the basis of the model, adaptive fuzzy control based on variable universe is applied to the wind turbine for improving wind energy capture. The fuzzy algorithm keeps the form of rules and varies universe of discourse according to the control error. It has the advantages of the fuzzy controller, including nonlinear control actions, less dependence on mathematical models and good robustness, but also fine accuracy. Simulation verifies that the algorithm improves control performance of wind turbine.
