摘要
In the light of the nonlinear properties and uncertain parameters of wind turbines, an active fault tolerant control technology is proposed to solve the dynamic stability problems, which is based on the linear-parameter-varying (LPV) gain scheduling technology. The linearized model around the operating point of wind turbines and faults is converted into a convex polyhedron structure LPV model by using LPV convex decomposition method. Then, each vertex of convex polyhedron was designed to meet the desired performances by using Linear Matrix Inequalities (LMIs). All the vertex gains are synthesized to build LPV controller with convex polyhedron structure. The simulation result shows that the LPV active fault tolerant controller can be applied to the wind turbines successfully.
