Fuzzy logic control of matrix-converter-based WECS in order to performance improvement

This paper describes a new Wind Energy Conversion System (WECS), where fuzzy logic principles and a Matrix Converter (MC) model are used for performance enhancement and efficiency optimization. The MC is used as the interface between the Permanent Magnet Synchronous generator (PMSG) and the grid. The power at the interface with the grid is controlled by MC to ensure that the active power injected into the grid is at its maximum amount. This system has a fuzzy logic controller that tracks the angular frequency with the wind velocity and controls the switching pattern of the matrix converter in order to extract maximum power. The complete control system has been analyzed, and validated by SIMULINK simulation study.
