Abstract

The complexity of modern mechatronic systems as well as rising reliability demands on diagnosis-implements, drastically enforce the development and application of automatic diagnosis functions. System-theoretical indicators complicating both the phenomenological and the automatic approach to fault diagnosis are for example: Nonlinear dynamics, a high state dimension and MIMO-behavior of a considered system. More often than not, the fault diagnosis problem is further complicated by tolerances and poor knowledge of the system, which furthermore increases the risk of false diagnosis. In this talk, the robust fault diagnosis of nonlinear systems is considered. Besides the synthesis of diagnostic functionalities, sufficient diagnosability conditions are introduced guaranteeing a correct fault diagnosis.
