DESCRIPTION:Abstract: In this talk I will speak about stability analysis of
a class of discontinuous discrete-time systems. In particular\, I will fo
cus on a scenario in which a linear plant is controlled via an affine stat
ic state feedback law taking values into a bounded countable set. The cons
idered setup is rather general and allows one to capture\, among others\,
the typical situation in which actuators may only deliver a finite set of
input values. The system under study is modeled as a feedback interconnect
ion of a linear system and a set-valued nonlinearity. Then\, an equivalent
representation\, based on a constrained optimization problem\, is propose
d to represent the set-valued nonlinearity via a collection of linear and
quadratic constraints. Relying on this description and on the use of gener
alized quadratic set valued Lyapunov functions\, sufficient conditions in
the form of linear matrix inequalities for global exponential stability ar
e obtained. Numerical examples corroborate the theoretical findings.Link S
