Robust Switching Gain‐Based Fractional‐Order Sliding Mode Control for Wind‐Powered Microgrids

Year: 2021

Type: article

Abstract: This study proposes a novel fractional‐order sliding‐mode control strategy with robust switching gain to achieve reliable and high quality of wind‐powered microgrid systems. Three fractional‐order sliding mode controllers are designed to generate continuous control signals and regulate the outer DC‐link voltage loop and inner current loop in the grid‐side inverters. High robustness and stability of the grid‐side inverter can be guaranteed even in the presence of parameter variations and external disturbances. Owing to the fractional‐order sliding manifold and fractional‐order integral control law, the chattering is attenuated. The fractional‐order robust adaptive switching gain is designed to avoid overestimating the upper bound of matched/unmatched uncertainties, save the control energy, and guarantee the rapidity and robustness of the convergence. Simulations validate the proposed method.
