# Integrating Model-Based Monitoring and Diagnosis of Complex Dynamic Systems

## Abstract

We present a new approach to model-based monitoring and diagnosis of dynamic systems. The presented DIAMON algorithm 1 uses hierarchical models to monitor and diagnose dynamic systems. DIAMON is based on the integration of teleological parameter-based monitoring models and repair-oriented device-based diagnosis models. It combines consistencybased diagnosis with model-based monitoring and uses an extension of the QSIM-language for the representation of qualitative system models. Furthermore, DIAMON is able to detect and localize a broad range of non-permanent faults and thus extends traditional diagnosis which exclusively deals with permanent faulty behavior. The operation of DIAMON will be demonstrated on a real-world example in a multiple-faults scenario.
