SMC for pitch angle of a variable speed PMSG-wind turbine considering actuator dynamics

Abstract

This paper aims to develop a novel pitch angle control for large variable speed wind turbine considering actuator dynamics. In fact, two Sliding Mode Controllers have been designed to achieve required performances. The first one is used below rated wind speed to maximize the extracted power. However, the second one is applied above rated wind speed to keep the power at the designed limits. Simulation results show good performances of the proposed control law.
