Abstract
When the wind speed is below rated value, the efficiency of captured wind energy must be maximized and the mechanical oscillation is guaranteed to be small. This essay deals with these problems, not only describes the advantages of the direct-driven permanent magnet synchronous wind power system, but also introduces two frequency loop model based on frequency separation principle, and suggests LPV model and LPV control method for high-frequency part of the system, the output of the high-frequency part is used to compensate the mechanical torque. The mathematical model is built with MATLAB, and the online test is carried out by dSPACE. The simulation results show that the controller reduces mechanical oscillation effectively, and enhances the system reliability.
