This paper focuses on control system design for wind turbine power regulation and the comparison of the techniques presented. A PI controller, Fuzzy controller and a combined Fuzzy-PI are applied to a 750KW fixed-speed horizontal axis wind turbine. The Fuzzy controller is proposed with two inputs, wind speed and output power error, with these inputs the(More)
Two methods based on state observers applied to fault diagnosis are presented in this paper. These methods are based on analysis of error signals known as residuals, which are generated from the comparison between the actual system output and the estimated output. A comparative study about these two methods applied to a hydraulic liquid level system is(More)
