Minimality of aperiodic sampled data systems
2017 American Control Conference (ACC), 2017This article studies the relation between the minimality properties of two different types of models encountered in the context of linear time-invariant (LTI) sampled-data systems with aperiodic sampling. More precisely, we consider the problem of determining the relationship between the minimality of a continuous-time LTI state-space (SS ...

Hankel norm of sampled-data systems
IEEE Transactions on Automatic Control, 1995Summary: We generalize the concept of Hankel norm for purely continuous-time systems to sampled-data systems. The Hankel norm of a sampled-data system is defined by taking into account the intersample behaviors. The formula of the Hankel norm of a sampled-data system is given by a hybrid state-space model approach. We show that the Hankel norm is equal

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.

Sampled-Data Systems: Maximal Sampling Period
2019 57th Annual Allerton Conference on Communication, Control, and Computing (Allerton), 2019This note presents a methodology for the design and the implementation of robust sampled-data systems with maximal sampling periods. The methodology applies to nonlinear input-affine systems. It is shown that optimal outcomes can be approximated by bang-bang controllers that are easy to design and implement.

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 ...

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.

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).

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.
