Original Kurzfassung:
It is well known that high performing control based on a nominal model may
underperform when system parameters change e.g. due to wear. Adaptive controls are a well
established way to tackle this problem, but their usage is not trivial, especially when they are
used for complex nonlinear systems with constraints like the air path of a combustion engine.
In particular, excitation can be insufficient for the update of a model with many parameters.
Against this background, we extend and test an approach based on directional forgetting on a
production engine, showing that this approach is viable for practical applications.
