Resumen En este artículo se presenta la aplicación de una de las técnicas de Soft Computing, la lógica fuzzy o lógica difusa, al control de un sistema complejo y altamente no lineal como es un aerogenerador. Se describe el funcionamiento de estos sistemas eólicos, especificando las diferentes zonas de comportamiento que dan lugar a no linealidades difíciles de controlar por un solo regulador. Se han desarrollado los pasos necesarios para describir cómo se diseña y aplica un sistema basado en lógica difusa que se pueda aplicar a todas las zonas. Este controlador regula el ángulo de cabeceo y el par del aerogenerador. Se muestran resultados de simulación que validan la aplicabilidad de esta técnica inteligente para estos sistemas.Abstract In this paper we present an application of Soft Computing techniques to a control problem. More specifically, we have applied fuzzy logic to control a wind turbine. These wind-driven generators are complex and highly non-linear systems. Firstly, the performance of these wind systems is described. They have different operating zones and therefore they are usually controlled by several controllers, one for each zone. The main goal of this paper is to develop an intelligent controller that works on every operating point. The design of a fuzzy controller for pitch angle and electric torque of a wind turbine is detailed. Simulation results are encouraging and show how this soft computing technique is suitable in order to control these types of complex systems.
