From stability analysis to resilient and delay-scheduled
control of linear time-delay systems
Nowadays, delays are omnipresent, from biology to economics sciences
and communication networks. Models involving delays are called
'time-delay systems' and have attracted more and more interest these
past years. This large amount of works has led to a wide arsenal of
techniques for analysis and control. This talk aims at providing a
glimpse on the field of control of linear time-delay systems. First,
the problem of stabilization will be presented with a particular
emphasis on the difficulties arising in the derivation of LMI-based
solutions. The important role of relaxations will be explained as a
tool for obtaining LMI-based results.
Finally, different new types of controllers, guaranteed to be
resilient with respect to uncertain delay knowledge, will be
synthesized. The first class, referred to as 'controllers with
memory', implements a delayed term whose delay is different from the
system one. The second technique, referred to as 'delay-scheduled
control', uses the known delay as a scheduling parameter on the
controller gains.
