Observability of affine discrete-time asynchronous switched systems
نویسندگان
چکیده
This paper deals with observability of affine discrete-time asynchronous switched systems, that is affine switched systems whose switching times may be different from sampling instants. Two observability notions are studied: pathwise observability and mode observability. We show that there exist some sampling frequencies that preserve pathwise observability if any subsystem is observable. Necessary and sufficient conditions are given for mode observability in the autonomous case. The theoretical results are illustrated through an example.

A new switching strategy for exponential stabilization of uncertain discrete-time switched linear systems in guaranteed cost control problem
Uncertain switched linear systems are known as an important class of control systems. Performance of these systems is affected by uncertainties and its stabilization is a main concern of recent studies. Existing work on stabilization of these systems only provides asymptotical stabilization via designing switching strategy and state-feedback controller. In this paper, a new switching strate...
متن کاملRealization Theory for Discrete-Time Piecewise-Affine Hybrid Systems
The paper investigates the realization problem for piecewise-affine discrete-time hybrid systems. A piecewise-affine discrete-time hybrid system is a discrete-time system such that the state-transition and readout maps are piecewise-affine maps. We will restrict our attention to autonomous systems and we will study the following realization problem. For a specified output trajectory, find a pie...
متن کاملObservability of Piecewise-Affine Hybrid Systems
We consider observability for a class of piecewise-affine hybrid systems without inputs. The aim is to give verifiable conditions for observability in terms of linear equations and inequalities. We first discuss a number of important concepts, such as discrete-event detectability and trajectory observability. We give sufficient conditions for observability, observability in infinitesimal time, ...
متن کاملObservability of Switched Linear Systems
The observability of deterministic, discrete-time, switched, linear systems is considered. Depending on whether or not the modes are observed, and on whether the continuous state or the mode sequence is to be recovered, several observability concepts are defined, characterized through linear algebraic tests, and their decidability assessed.
متن کاملRobust stabilization of discrete-time switched non-linear systems with time delay under asynchronous switching
This paper investigates the problem of robust stabilization of uncertain discrete-time switched non-linear systems with time delay under asynchronous switching. By using the average dwell time approach and piecewise Lyapunov functional technique, a state feedback controller is developed for the discrete-time switched system under asynchronous switching, and sufficient conditions for the existen...
