On wind turbine model predictive pitch control: an event-based simulation approach

Abstract

This paper is about a hierarchical structure with an event-based su-pervisor in a higher level and a model predictive control (MPC) in a lower level applied to a wind turbine. The event-based supervisor analyzes the operation conditions to determine the state of the wind turbine. The objectives and con-straints of the model predictive controller can also be adjusted by this supervi-sory controller. This hierarchical structure is able to ensure the performance and reliability required for a wind turbine to be integrated into an electric grid. Comparisons between model predictive pitch control and a default proportional integral pitch controller applied to a wind turbine benchmark are given and simulation results by Matlab/Simulink are shown in order to prove the effec-tiveness of the model.
