In this paper, a neural third-order sliding mode-direct torque control (NTOSM-DTC) for an asynchronous generator (AG) based dual-rotor wind turbine (DRWT) is proposed. The classical DTC strategy with traditional proportional-integral (PI) controllers has been widely applied to induction machines in recent years due to the high characteristics that it provides in comparison with the classical DTC switching technique. Meanwhile, it has a major drawback that are the significant current, rotor flux and torque ripples generated by the traditional PI controllers. To overcome these drawbacks, the improvement of this control technique by removing these controllers is designed in this paper. The proposed intelligenet nonlinear control technique is based on replacing the classical PI controllers with neural TOSM controllers which will have the same inputs as these controllers. The simulation was performed in Matlab software, and the results obtained make it possible to evaluate the characteristics of the proposed intelligenet nonlinear control technique over the traditional one.

For direct-drive wind turbines, effective methods can be adopted to reduce the generator speed fluctuation under the rated wind speed. However, there is a nonlinear relationship between the change of pitch angle of wind turbine and wind speed. In order to obtain the maximum power of the wind turbine, under the working condition of wind gust, this paper takes the principle of prior action of the pitch control and uses the variable gain pitch knowledge identification algorithm to achieve the effective control of the motor speed by designing the power pitch generator on the pitch controller to ensure that the pitch angle can be operated quickly under the rated power, and at the same time, the nonlinearities are added to the speed control process of the pitch angle generator. The gain factor of the pitch angle generator speed control process can ensure that the pitch control can work in advance under the wind gust environment. Finally, the simulation results show that the two gust control methods can achieve effective suppression of wind turbine generator in the case of overspeed, which can effectively increase the power generation of wind farms, reduce the load of wind turbines, and improve the operating stability of the system.

This work represents a new nonlinear control for the asynchronous motor (AM) drive. The designed nonlinear control is based on the combination between the backstepping control (BC) scheme and third-order sliding mod control (TOSMC). In this proposed nonlinear control, the torque and flux are controlled. Also, the torque, current, and flux ripples are minimized by a proposed BC-TOSMC strategy. The proposed BC-TOSMC strategy is more robust compared to the field-oriented control (FOC). The proposed BC-TOSMC strategy of AM drive has been simulated in MATLAB/Simulink software. The comparisons were made between the proposed BC-TOSMC strategy and the FOC strategy under different operating conditions. The results show that the proposed BC-TOSMC strategy minimized the flux, current, and torque ripples of the AM drive compared to the FOC strategy, with a reduction torque ripples ratio of about 57.14%. Also, the total harmonic distortion (THD) values of stator current using the proposed BC-TOSMC strategy and FOC technique are respectively 1.09% and 3.42%. In this case, utilizing the proposed BC-TOSMC strategy, the performance of the AM has improved from the FOC strategy.
