text: Reliability-adaptive systems allow an adaptation of system behavior based
on current system reliability. They can extend their lifetime at the cost of lowered
performance or vice versa. This can be used to adapt failure behavior according
to a maintenance plan, thus increasing availability while using up system capability
fully. To facilitate setup, a control algorithm independent of a degradation model
is desired. A closed loop control technique for reliability based on a health
index, a measure for system degradation, is introduced. It uses self-optimization
as means to implement behavior adaptation. This is based on selecting the priorities
of objectives that the system pursues. Possible working points are computed beforehand
using model-based multiobjective optimization techniques. The controller selects
the priorities of objectives and this way balances reliability and performance.
As exemplary application, an automatically actuated single plate dry clutch is
introduced. The entire reliability control is setup and lifetime experiments are
conducted. Results show that the variance of time to failure is reduced greatly,
making the failure behavior more predictable. At the same time, the desired usable
lifetime can be extended at the cost of system performance to allow for changed
maintenance intervals. Together, these possibilities allow for greater system
usage and better planning of maintenance.
