Duration:

Half a day.

Abstract:

Problems in estimation and control can often be formulated, analyzed and/or solved using methods which exploit the properties of properly chosen or constructed sets. For example, constraints and uncertainties–as well as the effects of the latter on a control system–can naturally be described using sets. Likewise, estimating the response of a system to disturbances, as well as the inherent error of the estimation algorithm can also be described within a set-based formalism. By looking at concepts like invariance, bounded-error estimation, uncertainty propagation, and robust control, the ubiquity of set theoretic methods in the control and estimation community is undeniable.

The goal of the proposed workshop is to provide a tutorial on the use set-based methods in estimation and control.  We first present the basic principles of computer representable sets and their arithmetics. This is followed by recent developments in set-theoretic methods for parameter/state estimation and control. The workshop finishes with a discussion of applications and future developments.

The workshop will address topics like:

·         Set based methods in parameter estimation

·         Set based methods in global optimal control

·         Set based methods in robust MPC

Due to tutorial nature of the workshop, the prerequisites for attending the workshop cover just basics of convex analysis, optimization and process control.
