Robust Regulation of Systems with Infinite Dimensions

Infinite dimensional systems
usually arise from models
involving partial
differential equations or
time delays. Robust control
is concerned with controller
design based on mathematical
models, where the inevitable
modeling errors are taken
into account during the
design phase. In robust
control one specifies a model
which in a certain sense
approximates the physical
plant to be controlled. Based
on the approximating model a
feedback control law is
developed, which is
satisfactory for a set of
models, that in a certain
sense are close to this
model. This project considers
the so-called H-infinity
method, which is generally
considered as an important
method for robust control of
finite dimensional systems.
However, in the infinite
dimensional case the method
is not yet fully developed.
As a case study the robust
control of a pasteurization
plant is considered.
