Convex polyhedron LPV controller design for variable speed wind turbine

摘要

According to the dynamic stability of power train, the paper puts forward a new gain scheduling LPV robus H∞ controller design method which allocates the close-loop poles to the satisfied dynamic response area. By taking use of the LPV convex decomposition method, this paper transforms the wind turbine into a convex polyhedron LPV model, and then designs state space feedback K for each vertex of convex polyhedron which can meet H∞ performance by using LMI method. Synthesize each designed feedback controller to get convex polyhedron LPV controller. The result of simulation validates the controller to be of a good control performance.
