DSD: A Parameter/State Estimation Tool For Model-based Fault Diagnosis in Non-linear Dynamic Systems

摘要

A software package is described that can be used for parameter/state estimation in an arbitrary non-linear dynamical system towards fault diagnosis. The methodology is based on the representation of system evolution in time as probability of transitions between sets of magnitude intervals in the state/parameter space. The software is developed in C++ for Windows'95 platform and can be run for several processes simultaneously. The display capabilities of the software and its implementation are illustrated using a second order system.
