Bond-graph modelling of sub-models using sensors

In this paper we develop the bond-graph modelling of sub-models using sensors as parts of different detectors (gas, temperature, motion, vibrations). These sub-models are modelled using bond-graphs and are simulated using 20Sim software. The advantages of bond-graph modelling of these sensors using 20Sim consist in the possibility to use sub-models used in different complex detectors and these sub-models of different nature could be modelled/integrated in a single (bond-graph) model and their behaviour can be analysed using 20Sim. The sensors are used to detect the state of a system and the information from the sensors is feeding the decision block/system. A sensor that measures the system response can affect or influence the behaviour of the system. The influence of such a sensor could be quantified studying the behaviour of the system and this behaviour can be described and studied using 20Sim, independently on the nature of the measure that influence the system. For example, the change of capacity could be used to measure forces, humidity, temperature and other king of physical measures. All these parameters can be modelled and studied using a single and unitary model (bond-graph) and simulation software 20Sim.
