Design MV-STR Pitch Controller For 100 KW Wind Turbine

Abstract

Abstract-In this paper the detailed model of the 100 KW wind <br><br>turbine with permanent magnet synchronous generator <br><br>constructed at the Sun and Air Research Institute of Ferdowsi <br><br>University of Mashhad, is extracted by using mathematical <br><br>equations and practical simulation. There are a lot of limitations <br><br>in this turbine performance and control. Therefore the controller <br><br>designing is a complex task and adaptive control with considering <br><br>system 1imitations will lead to an appropriate approach because in <br><br>that case both the limitations and uncertainties are investigated <br><br>during the design procedure. In this paper a practical pitch <br><br>controller is designed based on the self-tuning regulators (STR) <br><br>and minimum variance (MV) algorithm. The designed controller is <br><br>applied to the practical simulator and compared with the PI <br><br>controller. These controllers are utilized and compared to <br><br>regulation of the pitch angle in both simulation and practical <br><br>application. The results show that the MV-STR pitch controller <br><br>leads to smoother pitch signal and generator speed in the same <br><br>wind conditions. The novelty of this paper is achievement to a <br><br>detailed model and applying adaptive control method to an <br><br>experimental case.
