    ABSTRACT: Renewable energy sources have focused a special attention in wind energy conversion systems, where the goal is maximal power extraction. This paper presents an evaluation of the linear controllers eigen structure assignment, linear quadratic regulator, and the robust loop shaping design procedure actuating on a small wind energy conversion system with a permanent magnet synchronous generator, the rectification is made by a diodes bridge, and the direct current is controlled by a DC-DC converter. The analysis is made calculating the mean square error of the optimal tip speed ratio and the tip speed ratio developed by each regulator, the numerical results also show the performance of the power coefficient, power extracted from a wind profile, and the operation around the optimal regime characteristic. The proposed system works under variable wind speed, and validate the methodology applied.

    ABSTRACT: This paper presents a robust control system over the induction motor based on the H<sub>infin</sub> and loop shaping procedure. It has a set of simples steps to design the linear control law, the model used is the rotor-flux oriented coordinated system and is linearized by the Taylor's series. Finally the output feedback controller test shows the performance of the drive in presence of disturbances.
