ABSTRACT

Due to new technologies, the improvement of industrial systems is progressively complex. Accordingly, it has become difficult to manage and predict the behaviour of these systems, particularly when they will be exposed to failures. An identical dynamic model should reflect all characteristics of a planned integrated mechatronic system. Health monitoring of any system is essential in guaranteeing the safe, efficient, and correct operation of complex engineering systems. This paper presents a simulation of a non-linear, experimental based model of a coupled tank apparatus CE 105 by using LabVIEW 2014. In this study, a common modelling paradigm with several sources of fault was used to simulate both nominal and faulty behaviour. It is concluded that the liquid level, in the presence of a PID controller, will not be affected by the fault value until it reaches a certain threshold. Hence, the end of the useful life could be predicted by monitoring the PID voltage.
