In this paper, a new fault tolerant control scheme for wind energy conversion system (WECS) is proposed considering the partial failure of actuators. By building and analyzing the state equation of WECS, actuator continual gain faults of WECS is converted into system parameter uncertainties. The T-S fuzzy theory is employed for the modeling of WECS with this parameter uncertainties. Using parallel...
When wind speed is below the rated value, the efficiency of captured wind energy must be maximized and the mechanical oscillation be guaranteed to be small. To deal with these problems, This essay describes the advantages of the direct-driven permanent magnet synchronous wind power system, and then introduces the two-frequency-loop model based on frequency separation principle, The LPV model and LPV...
