Design and Control of Permanent Magnet Synchronous Generator for Variable Speed Wind Energy Conversion System Using Sliding Mode Control

The wind energy conversion system for the generation of electricity in variable speed needs the control of speed of permanent magnet synchronous generator inorder to maintain its efficiency. Inorder to maintain the efficiency proper control of the generator is necessary. One such promising controling method is sliding mode control. This control method, provides ideal characteristics for the application in the control of permanent magnet synchronous generator. The modelling of the wind energy system and corresponding sliding mode design is done. Appliction of this method for control using dynamic models of the d axis and q axis currents, the shaft rotational speed is controlled according to the wind speed.
