Reduction-Based Robustness Analysis of Linear Predictor Feedback for Distributed Input Delays

On robustness of predictor feedback control of linear systems with input delays

This paper is concerned with the robustness of the predictor feedback control of linear systems with input delays. By applying certain equivalent transformations on the characteristic equation associated with the closed-loop system, we first transform the robustness problem of a predictor feedback control system into the stability problem of a neutral time-delay system containing an integral op...

Robust predictor feedback for discrete-time systems with input delays

This work studies the design problem of feedback stabilizers for discrete-time systems with input delays. A backstepping procedure is proposed for disturbance-free discrete-time systems. The feedback law designed by using backstepping coincides with the predictor-based feedback law used in continuous-time systems with input delays. However, simple examples demonstrate that the sensitivity of th...

Distributed predictor-based stabilization of continuous interconnected systems with input delays

Robustness analysis of discrete predictor-based controllers for input-delay systems

In this paper, robustness to model uncertainties are analyzed in the context of discrete predictor-based statefeedback controllers for discrete-time input-delay systems with time-varying delay, in an LMI framework.The goal is comparing robustness of predictor-based strategies with respect to other (sub)optimal state feedback ones. A numerical example illustrates that improvements in tolerance t...

Observer based output feedback control of linear systems with input and output delays

This paper is concerned with observer based output feedback control of linear systems with both (multiple) input and output delays. Our recently developed truncated predictor feedback (TPF) approach for state feedback stabilization of time-delay systems is generalized to the design of observers. By imposing some restrictions on the open-loop system, two classes of observer based output feedback...
