风力机变桨距的线性二次型最优控制
Linear quadratic optimal control on variable-pitch of wind turbine
摘要
Abstract
The control of wind turbine' s variable-pitch has many problems,such as instability and randomicity of wind energy,larger disturbance and nonlinear of wind turbine's models,etc.For solving these problems,affine nonlinear systems of wind turbine' s models are proposed to be exact feedback linearization.Linear quadratic optimal control algorithm is designed based on nonlinear optimal control and validity of the algorithm is demonstrated by simulations.The simulated result proves that the linear quadratic optimal control algorithm can control that output power of wind turbine is kept within 10％ of the rated power.In addition,the algorithm has other advantages such as good precision,stability,and short response time.关键词
