The Reactability of Discrete Time Systems

IEEE Control Systems Letters, 2023
An important property of a dynamical system is its reactivity, i.e., the initial rate of growth of the norm of the state vector. However, most literature on reactivity has focused on continuous time systems. Here we define the reactivity of discrete time systems and apply it to characterize the dynamics of network systems and Markov chains.

On Stabilization of Discrete Time-Varying Systems

SIAM Journal on Control and Optimization, 2021
The presented paper considers problems of asymptotic, exponential, and uniform exponential stabilizability of discrete time-varying systems. Relations between different types of stabilizability, controllability, and linear-quadratic problem and the Riccati equation for discrete time-varying linear systems are discussed.

Linearization of Discrete-Time Systems

SIAM Journal on Control and Optimization, 1996
The algebraic formalism developed in this paper unifies the study of the accessibility problem and various notions of feedback linearizability for discrete-time nonlinear systems. The accessibility problem for nonlinear discrete-time systems is shown to be easy to tackle by means of standard linear algebraic tools, whereas this is not the case for ...

Discrete-time differential systems

Signal Processing, 2015
In this paper we formulate a coherent discrete-time signals and systems theory taking derivative concepts as basis. Two derivatives - nabla (forward) and delta (backward) - are defined and generalized to fractional orders, obtaining two formulations that are discrete versions of the well-known Grunwald-Letnikov derivatives.
