Power extraction has become a critical consideration in tidal stream turbine (TST) systems. In practice, the lumped disturbances under varying current conditions may deteriorate maximum power point tracking (MPPT) performance and cumulate fatigue damage over-rated power. Besides, conventional pitch controllers are sensitive to parameter uncertainties of nonlinear TST system. this paper, novel o...
