This paper deals with unknown input interval observer synthesis for discrete-time switched systems. First, a decomposition leading to obtain subsystem not affected by the is presented. Second, an designed based on Input-to-State Stability (ISS). The gains are computed solving Linear Matrix Inequalities (LMI) formulated multiple quadratic Lyapunov functions under average dwell time switching sig...

<p style='text-indent:20px;'>In this paper, an optimal control model ruled by a class of linear discrete-time stochastic descriptor systems is considered under quadratic index performance. Employing dynamic programming method, recurrence equation to simplify the problem presented provided that are both regular and impulse-free. When objective function quadratic, according equation, linear...

Abstract For linear control systems in discrete time controllability properties are characterized. In particular, a unique set with nonvoid interior exists and it is bounded the hyperbolic case. Then formula for invariance pressure of this proved.
