Due to nonlinear dynamics and the presence of parametric uncertainties and perturbations in this system, sliding mode control is employed. To generate a smooth control signal, dynamic sliding mode method is used. Uncertainties bound is not required in the suggested algorithm, since the adaptive gain in the controller relation is used in this study. Convergence of the sliding variable to zero and adaptive gain to the uncertainty bound are verified using Lyapunov stability theorem. The proposed controller is evaluated in a comprehensive simulation on the BDFIG model. Moreover, output performance of the proposed control algorithm is compared to the conventional and second-order sliding mode and&nbsp;proportional-integral-derivative (PID) controllers.</span></span></span></span></p> Brushless Doubly-Fed Induction Machine,Dynamic Sliding Mode Control,Adaptive Gain,Uncertainty 2405 2405 http://ijeee.iust.ac.ir/browse.php?a_code=A-10-4165-1&slc_lang=en&sid=1 M.
