Abstract

In this paper an object-oriented (OO) Fault Detection and Isolation (FDI) method for complex systems is developed. Examples of such systems are mechatronic systems, commercial vehicles and chemical process plants. Such systems consist of numerous subsystems from different physical domains. Each subsystem is described by an object. The mathematical composition of these objects results in a differential algebraic equation (DAE) which describes the overall system. This DAE is automatically analyzed and transformed into a set of residual generators (RG) in integral causality which meet a given isolability specification.
