Modeling Switched Behavior with Hybrid Bond Graph : Application to a Tank System
Different approaches have been used in the development of system models. In addition, modeling and simulation approaches are essential for design, analysis, control, and diagnosis of complex systems. This work presents a Simulink model for systems with mixed continuous and discrete behaviors. The model simulated was developed using the bond graph methodology and we model hybrid systems using hybrid bond graphs (HBGs), that incorporates local switching functions that enable the reconfiguration of energy flow paths. This approach has been implemented as a software tool called the MOdeling and Transformation of HBGs for Simulation (MOTHS) tool suite which incorporates a model translator that create Simulink models. Simulation model of a three-tank system that includes a switching component was developed using the bond graph methodology, and MoTHS software were used to build a Simulink model of the dynamic behavior.
