Advanced control strategies and modern consulting provide
new challenges for the classical problem of bumpless transfer.
It can, for example, be necessary to transfer between an only
approximately known existing analogue controller and a new
digital or adaptive controller without accessing any states.
Transfer ought to be bi-directional and not presuppose steady
state, so that an immediate back-transfer is possible if the new
controller should drive the plant unstable.
In this paper we present a scheme that meets these requirements.
By casting the problem of bi-directional transfer into an associated
control problem, systematic analysis and design procedures
from systems theory can be applied. The paper includes laboratory
and industrial applications.
