Fig. 11 shows the operator-controller module
for the active suspension system. Three different
controllers can be selected: the controllers ”rela-
tive damper” and ”absolute damper with reference
trajectory” implement the concepts detailed above.
If underlying modules or the sensor-fault detectors
signal a system failure, the active suspension will be
shut off and the controller ”system failure” selected.
The controller choices are reflected in the reflective
operator. Each controller has a part in the reflective
operator dedicated especially to itself. The displace-
ment sensors as well as the acceleration sensors
each have their own fault detection systems, testing
plausibility and computing parity equations. The con-
troller ”absolute damper with reference trajectory”
requires additionally a communication/transmission
part that contacts the stationary agents and receives
the respective track reference trajectory from it. The
necessary procedure to start the suspension system
after a system failure is part of the reflective operator
dedicated to the controller ”system failure”.
Along with the reference trajectory, it is of course
also possible to optimize the controller parameters
themselves. This is done in the cognitive operator
”damper parameter optimization”. An example of the
implementation and the necessary software to recon-
figure the controllers for a hydraulic system can be
found in (Hestermeyer et al., 2004).
6 CONCLUSION
A consistent structuring of the controlling informa-
tion processing of mechatronic systems makes man-
ageable the whole range of complex systems up to
self-optimizing systems. Extension of classical de-
sign views, such as block diagrams, allows integration
of conventional design and analysis methods and per-
mits the designer to stick to his familiar views. The
next step will be the prototypical realization of a mod-
elling tool of reconfigurable systems according to the
concept presented. Already implemented OCM on
other platforms will subsequently be transferred into
it. This will allow us to verify and refine our concept.
