Abstract
A concept for implementation of multivariable controllers is
presented in this paper. The concept is based on the
Youla-Jabr-Bongiorno-Kucera (YJBK) parameterization of all
stabilizing controllers. By using this architecture for
implementation of multivariable controllers, it is shown how it is
possible to smoothly switch between multivariable controllers
with guaranteed closed-loop stability. This includes also the case
where one or more
controllers are unstable.
The concept for smooth online changes of multivariable controllers
based on the YJBK architecture can also handle the start up and shut down of
multivariable systems. Furthermore, the start up of unstable
multivariable controllers can be handled as well.
Finally, implementation of (unstable) controllers as a stable Q
parameter in a Q-parameterized controller can also be achieved.
