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...
A model of a stand-alone Proton Exchange Membrane Fuel Cell PEMFC power supply for AC motor application is studied in this paper. As an AC load, a permanent magnet synchronous motor PMSM is chosen. The power conversion chain is basically composed of DC-DC boost converter and DC-AC inverter to increase and regulate the generated voltage by the PEMFC in order to satisfy the load requirements. Then,...
In this paper, the model and the control of the direct-drive wind energy conversion system with permanent magnet synchronous generator PMSG are studied and implemented on MATLAB/ Simulink software. The model includes a wind turbine with horizontal axis driving PMSG through a power transmission device and debits through a rectifier connected to the dc-bus. A vector control strategy is applied. The...
