ABSTRACT
Nonlinear Process Control
-- On the Way to a Practical Disciplin --
Frank Allgower
Automatic Control Laboratory
ETH Zurich
The dynamic behavior of most technical, and in particular chemical,
processes is of nonlinear nature. Often nonlinearities do not play
a prominent role, but in some cases the nonlinear effects are so
dominant that control tasks, like stabilization and achievement of
satisfying control performance, cannot be accomplished with linear
controllers. For these processes nonlinear controller design
techniques are mandatory.
During the last 10+ years a number of new nonlinear controller
design techniques have been developed. Although most of these
methods are very appealing from a theoretical point of view, only
few real world process control applications based on those results
are reported on.
In this talk we will discuss reasons for this lack of practical
application/applicability of some of these methods and will
show that suitable extensions and modifications can improve the
practicability considerably.
