Stability and Stabilisability Through Envelopes for Retarded and Neutral Time-Delay Systems
Participants : Catherine Bonnet, Caetano Cardeliquio, Silviu Niculescu, André Fioravanti [FEM-UNICAMP, Brazil] .
We presented a new approach to develop an envelope that engulfs all poles of a time-delay system.
Through LMIs we determined envelopes for retarded and neutral time-delay systems.
The envelopes proposed were not only tighter than the ones in the literature but they can also be applied to verify the stability of the system.
The approach was also used to design state-feedback controllers which cope with design requirements regarding .
