Delayed finite-dimensional observer-based control of 2D linear parabolic PDEs
Pengfei Wang, Emilia Fridman
Recently, a constructive method was suggested for finite-dimensional observer-based control of 1D linear heat equation, which is robust to input/output delays. In this paper, we ai…
A Robust Time-Delay Approach to Extremum Seeking via ISS Analysis of the Averaged System
Xuefei Yang, Emilia Fridman
For N-dimensional (ND) static quadratic map, we present a time-delay approach to gradient-based extremum seeking (ES) both, in the continuous and, for the first time, the discrete…
New Stability and Exact Observability Conditions for Semilinear Wave Equations
Emilia Fridman, Maria Terushkin
The problem of estimating the initial state of 1-D wave equations with globally Lipschitz nonlinearities from boundary measurements on a finite interval was solved recently by usin…
Generalized Jensen Inequalities with Application to Stability Analysis of Systems with Distributed Delays over Infinite Time-Horizons
Kun Liu, Emilia Fridman, Karl Henrik Johansson +1
The Jensen inequality has been recognized as a powerful tool to deal with the stability of time-delay systems. Recently, a new inequality that encompasses the Jensen inequality was…
Networked control systems in the presence of scheduling protocols and communication delays
Kun Liu, Emilia Fridman, Laurentiu Hetel
This paper develops the time-delay approach to Networked Control Systems (NCSs) in the presence of variable transmission delays, sampling intervals and communication constraints. T…
A Round-Robin Type Protocol for Distributed Estimation with Consensus
V. Ugrinovskii, E. Fridman
The paper considers a distributed robust estimation problem over a network with directed topology involving continuous time observers. While measurements are available to the obser…
