Delay as an Explicit Parameter in the Controller for LTI Delay Systems

Abstract

This talk demonstrates the possibility of developing controllers that can adaptively tune to the inherent feedback delays of a class of LTI systems. æThat is, the delay parameter explicitly appears inside the controller, by which the closed-loop system can either be made delay independent stable, or designed to remain stable for pre-defined range(s) of delays. We prove this design approach mathematically based on a non-conservative frequency domain approach, and verify theoretical results through simulations.
