The condition of mechatronic production equipment slowly deteriorates over time, increasing the risk of failure and associated unscheduled downtime. A key indicator for an increased risk for failures is the shifting of resonances. The aim of this paper is to track the shifting resonances of the equipment online and during normal operation. This paper contributes to real-time parametric fault diagnosis by applying and comparing parameter estimators in this new context, highly relevant for next-generation mechatronic systems. The proposed fault diagnosis systems consist of recursive least squares algorithms and the effectiveness is illustrated on an overactuated and oversensed flexible beam setup, allowing to artificially manipulate its effective resonances in a controlled manner.

... Thirdly, feedback controllers in mechatronic systems are designed to minimise the effects of disturbances and anomalies, making fault detection more difficult [14]. At the same time, faults in closed-loop controlled systems may be particularly hazardous as these affect machine performance and stability margins [15]. ...
