摘要：

This article focuses on the efficiency enhancement using fault-tolerant sliding mode control (SMC) for permanent-magnet vernier generator (PMVG)-based wind turbine system (WTS) under actuator faults. To do this, the dynamical model of the WTS is constructed with the actuator fault model. Next, the optimum tip speed ratio-based SMC method is proposed to calculate the optimum speed reference of the maximum power point tracking controller that achieves the maximum power capture of the WTS. And then, to effectively track the optimum rotor speed under actuator faults, a disturbance attenuation-based sliding surface is proposed with a novel time-varying exponential reaching law. At the same time, the stability conditions of the SMC are also derived using the appropriate Lyapunov function. Finally, the resilient performance and superiority of the proposed control method are demonstrated through simulation for 5-kW PMVG-based and 4.8-MW benchmark WTSs and its applicability is proven through an experimental prototype for the 5-kW PMVG-based WTS.
