Fractional‐order fault‐tolerant pitch control design for a 2.5 MW wind turbine subject to actuator faults
This paper proposes an active fault‐tolerant pitch control design for a 2.5 MW wind turbine. The proposed scheme combines the robustness properties of fractional‐order terminal sliding mode control with the accurate estimation of virtual actuators. Its main objective is to enable the wind turbine to retain its nominal pitching performance under faulty conditions whereas simultaneously attenuating chattering. The fault detection scheme implements a bank of modified unscented Kalman filters. The proposed approach was implemented to a 2.5‐MW wind turbine subject to pitch actuator faults and sensor noise. Its performance was compared with that of an integer‐order terminal sliding mode approach. Guaranteeing the finite time stability of the pitching system under faulty conditions whereas alleviating the chattering phenomena are among the positive features of the proposed fractional‐order fault‐tolerant pitch control design.
