A real-time algorithm for fault identification in machining centres

Abstract The ability to identify a fault in the manufacturing systems is a hot problem in both academic research and industrial practice. The paper presents a timed model and algorithm, derived from the classical diagnoser approach, with the explicit modeling of time-out and the explicit modeling of nominal and non-nominal control behavior. The aim is to find a practical and concrete way to write a software (SW) algorithm which is able to isolate promptly and online a fault as soon as an alarm is raised by alarm handling functions, with focus on industrial automation applications. The whole set of automated equipments of a real work machine has been considered as a test case.
