A sliding mode model reference adaptive control of PMSG wind turbine

Abstract

In this study, a model reference adaptive sliding mode speed controller (SM-MRAC) for a direct drive wind energy conversion chain is presented. The system model includes a wind turbine with horizontal axis driving a permanent magnet synchronous generator (PMSG) through a rectifier connected to the dc-bus. The designed SM-MRAC controller is compared with a conventional PI controller. The model and the control of the proposed system are implemented on MATLAB/SIMULINK software. The simulation results improve the effectiveness of the SM-MRAC and show the performance specification comparison with the conventional PI controller.
