Fault Detection for Precision Mechatronics: Online Estimation of Mechanical Resonances

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