“…Based on the rotor configurations, the TCT can be grouped as vertical axis turbines 142 (VATs) and horizontal axis turbines (HATs) [43]. Recently, diverse vertical axis and horizontal axis tidal current turbines (TCTs) have been improved and described in the literature [44][45][46][47][48]. Other abbreviations are also used for horizontal axis turbines reported in the literature like horizontal axis tidal turbine (HATT) and horizontal axis tidal stream turbine (HATST) concept [49].…”

“…In fact, various demonstrative TST projects have been successfully industrialized and they are entering the pre-commercial stage [3][4]. For achieving compact structure and reducing maintenance requirements, several TST projects adopt turbines with nonpitchable blades and choose permanent magnet synchronous machine as generator [5].…”

As an emerging technology to harness the marine current energy, tidal stream turbine (TST) systems have been developed due to high predictability and energy density in tidal current resources. However, considering that various challenges such as swell disturbances, unknown disturbances, or parameter uncertainties may deteriorate the system performance, it is interesting to investigate alternative control strategies to the conventional proportional-integral (PI) controls. In this paper, the active disturbance rejection control (ADRC) approach is proposed to replace PI controllers in the conventional generator-side control scheme. In this approach, two ADRC schemes (cascaded and second-order ADRC strategies) are respectively applied and compared to achieve MPPT under current velocity and turbine torque disturbances.Performances of the proposed ADRC approaches are compared to PI and sliding mode control strategies. Energy production during swell wave disturbance is also evaluated under these control strategies. The comparisons show that the cascaded ADRC has better performance than the second-order approach. Moreover, the cascaded ADRC is tested under parameter variations to evaluate its robustness. The carried out simulation-based comparative study shows the effectiveness and advantages of the cascaded ADRC strategy over conventional PI controller in terms of fast convergence, overshoots elimination, and improved robustness under disturbances and parameter uncertainties.
