In this paper, we consider discrete time systems with polytopic time varying uncertainty. We look for a class of parameter dependent Lyapunov functions which are quadratic on the system state and depend in a polytopic way on the uncertain parameter. We show that extending the new discrete time stabi

✦ Synopsis
The general equations for the parametric sensitivity functions of a broad class of hybrid discrete/continuous dynamic systems where the continuous part is described by differential-algebraic equations (DAEs) are presented. For the cases where this continuous part is an ordinary differential equation system (ODEs) or a linear time invariant DAE, sufficient conditions for the existence and uniqueness of the sensitivity functions are derived. Numerical computation of these sensitivity functions has been implemented as a generic functionality in a mathematical modeling environment. Special cases and application examples are used for illustration.

Frequency domain functions are developed which play an analogous role in sampled data control as do the common sensitivity and complementary sensitivity functions in traditional control.
We provide explicit closed form expressions for strict Lyapunov functions for time-varying discrete time systems. Our Lyapunov functions are expressed in terms of known nonstrict Lyapunov functions for the dynamics and finite sums of persistency of excitation parameters. This provides a discrete tim
In general, a hybrid dynamic system is a system with different kinds of time dynamics? e.g., continuous, discrete, or impulsive, in different interacting parts of the system.

Discrete-time models of continuous-time plants are commonly required owing to the popular use of computers to implement control and estimation algorithms. When stochastic design techniques such as the discrete-time Kalman filter are utilized, it is necessary to determine the equivalent discrete-time
