“…In favor of the hybrid character of this system, this hydraulic process is modelled by the HBG tool. Closely, the water treatment system contains many principal units that are well introduced in Fathallah and Zanzouri (2017). But, this study focuses only on the raw water treatment and the water distribution systems, as shown in Figure 10.…”

“…In Junco et al (2008), the authors extended the previously presented Lyapunov’s Second Method to the HBG to conclude about stability. In addition to the states’ estimation and the residues’ generation, the BG observers are used in the procedure of the mode identification (Fathallah and Zanzouri, 2017). For the HBG community, the issue of the current mode identification has recently been elaborated in many works like Borutzky (2014), which showed that the Analytical Redundancy Residual (ARR) derived from a BG cannot only serve as fault indicators but may also be used for BG model-based system mode identification.…”

This paper presents a new concept for calculating of the bond graph observer gains based on a graphical approach that investigates the Lyapunov Second Method in order to conclude about the observer stability and to search for the adequate gains that stabilize the observer. This new observer is used in the mode identification procedure. In fact, the observer’s residues allow the differentiation between the current mode and the other system modes. In order to guarantee the efficiency of the mode identification procedure, a new bond graph approach is proposed. It concerns the discernibility between the modes in bond graph language. First, it deals with the R-discernibility that introduces the definition of the discernibility through the structural parity residual then returns to a simple calculation of some matrices’ ranks in bond graph language. Second, another bond graph technique is applied to define the discernibility throughout the equivalency between the realizations.
