Discrete-time system
WebA discrete-time dynamical system consists of a number of state variables ( x1, …, xn) defined on the state space and a system of difference equations. Here Δ xn represents … WebThe definition for discrete-time systems is almost identical to that for continuous-time systems. The definition below provides this, using an alternate language commonly used in more mathematical texts. Let ( X, d) be a metric space and f : X → X a continuous function. A point x in X is said to be Lyapunov stable, if,

In Section 8.3.2 we show how to discretize continuous-timelinear systems in order to obtain discrete-time linear systems. 8.3.1 Difference Equations and State Space Form An th-orderdifference equation is defined by
Webthe important ideas in discrete-time systems apply equally to continuous-time systems. Alas, even discrete-time systems are too diverse for one method of analy sis. Therefore even the abstraction of systems needs subdivision. The par ticular class of so-called linear and time-invariant systems admits power ful tools of analysis and design. WebJul 17, 2024 · The discrete-time models of dynamical systems are often called D ifference Equations, because you can rewrite any first-order discrete-time dynamical system with a state variable x ( Eq. (3.1.1) ), i.e., xt = F(xt − 1, t) into a “difference” form. ∆ x = xt − xt − 1 = xt = F(xt − 1, t) − xt − 1. which is mathematically more ...
