Abstract
Mechatronic devices integrate control systems are fundamentalto safe operational condition of complex vehicles, especially aircrafts. In order to ensure reliability of aircraft mechatronic systems, with consequent improvement in safety, it is necessary to pay special attention to failures in these devices and their consequences in other subsystems from the early design phases. An important element to consider is the electromagnetic compatibility, which deals with electrical and magnetic relations among components or between subsystems operating in the same electromagnetic environment that may produce interference and malfunction. This paper presents a literature review on fault analysis in mechatronic and electronic control systems caused by electromagnetic problems, followed bythe description of aknowledge-based system (KBS) prototype for the early design phases focused on electromagnetic compatibility and reliabilityof mechatronic systems. The prototype includes a knowledge base on mechatronic design. Rules, object-oriented modeling and semantic networks are implemented as knowledge representation techniques. Results are evaluated and discussed byexperts in mechatronics and design. The paper also discusses issues on expandability and validation of KBS prototype.
