Abstract: This contribution describes the design and implementation of a multi-model based fault detection and diagnosis system for a hydraulic servo axis.
A parameter estimation method is presented by an example of an electrohydraulic position servo. The method is based on the Markov chain Monte Carlo.

Abstract: In the present work, we use an adaptive robust approach for fault detection and accommodation in electro-hydraulic systems.
The unknown parameters of physical laws which govern the dynamics of processes can be gained from measured input and output signals in a two step procedure.
