The notion of zeros of sampled-data systems is introduced in the lifting framework so that from the continuous-time viewpoint the zeros have signal transmission blocking properties. A characterization of all such zeros is given in terms of the eigenvalues of a bounded operator on the state space.

Invariance of sampled-data and adaptive sampled-data systems
IFAC Proceedings Volumes, 1963Summary In the report it is shown that the invariance conditions can be used successfully in usual continuous control systems and also in sampled- data control systems. This is especially important in adaptive impulse systems. In the first section of the report fundamentals of invariance theory of combined sampled-data systems are considered.

Consider the basic laws of Physics that describe the behavior of physical objects: Newton’s laws, Lagrange’s equations, the Navier-Stokes equations, Maxwell’s equations, Kirchhoff’s laws etc. Each of these laws describe continuous-time phenomena. At present it is cost effective to manipulate signals in digital form: for this purpose, signals are ...

An FDI approach for sampled-data systems
Proceedings of the 2001 American Control Conference. (Cat. No.01CH37148), 2001In this paper, problems related to fault detection and isolation (FDI) in sampled-data (SD) systems are studied. A tool to analyze SD systems from the viewpoint of FDI and based on it a direct design approach of FDI system are developed. Key of these studies is the introduction of an operator which is used to describe the sampling effect.

Analysis of sampled-data interconnected systems
2008 47th IEEE Conference on Decision and Control, 2008In this paper, we consider the sampled-data problem of interconnected systems, specifically, time- and space-invariant systems. Our main contribution is to provide sufficient conditions on well-posedness, stability, and contractiveness of sampled-data interconnected systems in the form of a group of linear operator inequalities (LOIs).

Advances in computer-based control systems require to consider digital controllers on the base of multirate and unconventional sampling schemes. The purpose of this paper is to extend the concepts of system passivity which are well known ideas in the context of continuous and discrete time systems to the case of sampled-data systems.

Nonlinear H∞ filtering of sampled-data systems
Automatica, 1999Abstract This paper considers the problem of H∞ filtering for nonlinear samplcd-data systems. Sufficient conditions are obtained for the existence of filters that guarantee the L2 gain from an exogenous input to an estimation error is less than or equal to a prescribed value.

Having studied the separate components of a data acquisition system, we now consider the errors which are inherent in all sampled data systems. These are sampling and quantization errors. They can be reduced, but not eliminated. Examples of the design of complete systems are considered in which these errors are reduced to a level which is tolerable for

QUADRATIC STABILIZATION OF SAMPLED-DATA SYSTEMS WITH QUANTIZATION
IFAC Proceedings Volumes, 2002The influence of sampling and quantization on stability for linear time-invariant systems is investigated. In the first part, a bound for the sampling period for the closed-loop system without quantization is derived. By solving a Riccati equation, an optimal gain is calculated.

In Chap. 2 we dealt with discrete systems only, covering difference equations and the z transform. Chapter 3 we did examine finding discrete simulations of continuous systems, but we did so from a discrete perspective. In digital control systems where there are both discrete (the control algorithm) and continuous components (the plant), with a loop ...
