Fault Tolerant Control of Variable-Speed Variable-Pitch Wind Turbines: a Subspace Predictive Control Approach

Grid integration of wind power, especially using offshore wind farms, is dramatically increasing all over the world. Consequently, the reliability and robustness of wind turbines against faults are becoming important issues these days. In this paper, a new wind turbine Fault Tolerant Control (FTC) strategy based on adaptive Subspace Predictive Control (SPC) is proposed. The proposed strategy uses a model predictive control algorithm with its …
