Controller Coverings and Switched Control
Systems
In its simplest form, the
controller covering problem is as follows:
Given a subset M of admissible process model transfer
functions in a metric space T equipped with a metric \mu, find if possible
a finite set of controller transfer functions K with the property
that, for each transfer function t \in M, there is at least one controller
transfer function \kappa \in K which endows the closed-loop system transfer
function (t \kappa)/(1+ t \kappa) with at least stability and
possibly other prescribed properties. Such families K are called
controller covers of M.
The aim of this talk is to discuss the controller covering problem, and how its solutions
might be used to develop switched adaptive algorithms for controlling
poorly modeled processes.
