Objective:The complexity and size are increasingly important in industrial processes; they lead to the supervision of a growing number of variables whose knowledge is generally based on measurements and/or on processes models. Introduction:Different monitoring methods are generally based on output measurements and/or process modeling. Materials and Methods:With the lack of precision and the monitoring speed in most work due to the model or measurement noise, for this we aim to develop a new and more powerful detection model based on clocks, to ensure a rapid detection and determine fault duration to facilitate the fault identification. Result:This paper proposes a monitoring approach for interruption, permanent and/or intermittent faults in hybrid dynamical systems, whose principle is based on system modeling using hybrid automaton with stopwatch.The obtained results show that the monitoring system is able to detect rapidly the considered types of faults. Conclusion:A classic example is dedicated to illustrate our approach; the obtained results confirm the effectiveness of the proposed work.
