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


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.
