Frequency response of sampled-data systems
This paper introduces the concept of frequency response for sampled-data systems, and explores some basic properties as well as its computational procedures. It is shown that i) by making use of the lifting technique the notion of frequency response can be naturally introduced to sampled-data systems in spite of their time-varying characteristics, ii) it represents a frequency domain steady sta...
متن کاملComputation of Frequency Response Gain of Sampled-data Systems
Abstract: This paper provides a condition to determine the frequency response gain of sampled-data systems is less than a given positive number for its bisection computation. In contrast to existing conditions, there is no assumption on the norm of the related state space compression operators. The derived condition also unifies the computation of the frequency response gain of sampled-data sys...
متن کاملApproximation of frequency response for sampled-data control systems
This paper proves that the frequency response gains of fast-sample/fasthold approximations of a sampled-data system converge to that of the original system as the sampling rate gets faster. While this may appear to hold trivially, there is a serious technical difficulty, and the proof is indeed nontrivial. It is also guaranteed that this convergence is uniform on the total frequency range. The ...
متن کاملStructural Properties of Multirate Sampled-Data Systems
The application of Networked Control Systems (NCS) in which sensory and control signals are transmitted via shared data communication networks, is growing significantly and these systems have been the subject of research during the last decade. On the other hand, multirate sampled data systems have been investigated since a long time. In this paper, conditions under which a networked control sy...
متن کاملH and H∞ Design of Sampled-Data Systems Using Lifting Part I: General Framework and Solutions
This paper presents a complete solution to the H and H∞ problems for sampled-data systems. As opposed to previous work in the area, it is assumed here that all or some of the sampling function, the discrete-time controller and the hold function are available for design. The solution is obtained by transforming the problem to discrete-time using the wellknown lifting technique. It is then shown ...
