Fault tolerant control of wind energy conversion system — Fuzzy approach

Fault detection becomes more complex when nonlinear wind energy conversion systems (WECS) are subjected to parameter uncertainties. The problem of fault detection and isolation (FDI) still remains an active research area. A robust active fault tolerant fuzzy control (RAFTFC) of variable-speed wind energy conversion systems (WECS) in the presence of wide wind variation, wind disturbance, parametric uncertainties, and sensors faults is proposed. The WECS is modeled and analysed. The proposed system helps in controlling plant over a wide range of wind speeds and also increases the stability over a wide range of uncertainties.
