Delayed finite-dimensional observer-based control of 2D linear parabolic PDEs

no code implementations14 Jan 2024 Pengfei Wang, Emilia Fridman

To compensate the output delay that appears in the infinite-dimensional part of the closed-loop system, for the first time for delayed PDEs we suggest a vector Lyapunov functional combined with the recently introduced vector Halanay inequality.

Extremum seeking in the presence of large delays via time-delay approach to averaging

no code implementations14 Oct 2023 Xuefei Yang, Emilia Fridman

Given large delays, we choose appropriate gains to guarantee stability of this linear system.

A Robust Time-Delay Approach to Extremum Seeking via ISS Analysis of the Averaged System

no code implementations3 Feb 2023 Xuefei Yang, Emilia Fridman

As in the recently introduced (for 2D maps in the continuous domain), we transform the system to the time-delay one (neutral type system in the form of Hale in the continuous case).
