“…Systems with time delays constitute basic mathematical models of many real phenomena in circuits theory, economics, mechanics, and so forth, so they have been extensively studied in the literature: see, for example, [1][2][3][4] and references therein for several theoretical studies on this subject. An aspect that has not been frequently taken into account is the fact that, in many of these systems, the actuators have strict limitations.…”

“…Moreover, to reduce conservatism, some free matrices P i are used (only one of them restricted to be positive definite). This introduction of free matrices can be viewed as an extension of the model description introduced in [6], or similar to the slack variables used in [1,3], albeit in a different context. Finally, a LMI optimization approach is proposed to design the state feedback gain that maximizes the size of the estimated domain of attraction.…”

“…In this regard, bounding technique of cross terms [3], descriptor system approach [4], neutral model transformation [5], free-weighting matrix techniques [6]- [7], augmented Lyapunov functional approach [12]- [13], [16]- [17] have given major contributions in this field.…”

“…A partir de las cotas del retardo, se derivan condiciones de análisis y diseño menos conservadoras, que además, incluyen información de la derivada del retardȯ τ (t) ≤ µ < 1. Por ejemplo, mediante funcionales de Lyapunov-Krasovskii se obtienen condiciones de análisis LMI [127,130]. No obstante, algunas veces se introducen variables de decisión que no contribuyen a reducir el conservadurismo de los resultados de análisis.…”

“…Cabe destacar que no siempre dichas técnicas implican una reducción del conservadurismo, tal y como se ha visto anteriormente. En [143], se demuestra mediante el Teorema de Eliminación sobre otros resultados similares ( [130], y referencias similares) que existen variables de decisión que no aportan ninguna mejora, contribuyendo en todo caso negativamente debido al aumento de los errores numéricos por exceso de variables y al coste computacional. En sistemas discretos, un resultado equivalente se presenta en [47], donde se ilustra la equivalencia respecto otros resultados análogos en términos de conservadurismo pero con mayor número de variables de decision ( [135], y referencias similares).…”
