Stability and Robust Stabilisation Through Envelopes for Retarded Time-Delay Systems

摘要

This work deals with stability and robust stabilisation of retarded time-delay systems by applying a new method for obtaining an envelope that bounds all the system poles. Through LMIs we are able to determine envelopes that can be applied to verify the stability of the system and can also be utilised to design robust state-feedback controllers which cope with design requirements regardingα - stability.
