D. Rotondo, H. S. Sánchez, F. Nejjari, V. Puig

Resumen

En este artículo se presenta un tutorial sobre análisis y diseño de sistemas lineales con parámetros variantes (LPV) utilizando las desigualdades lineales matriciales (LMIs). Varias especificaciones, tales como la D-estabilidad, el desempeño H garantizado y el coste cuadrático garantizado, así como también diferentes estructuras de control, tales como el control por realimentación de estado, el control por realimentación de salida y el control basado en observador, han sido consideradas. Para ilustrar de forma didáctica el desarrollo completo del diseño mediante LMIs, se utilizan un ejemplo numérico y un modelo simplificado de un helicóptero de dos grados de libertad (TRMS).
