From Physical Modeling to Real-Time Simulation : Feed back on the use of Modelica in the engine control development toolchain

This article provides feedback from using Modelica i n the "System Modelling" area, involving modelling (behavioural and dynamic modelling), direct simulations, control and real-time applications. The described work was undertaken within three Europeans projects: Eurosyslib, Modelisar and Open Prod. Our aims are to attest Modelica language in an overall model of a vehicle consisting of vehicle dynamics, combustion engine, transmission, drive line, brakes and control systems. ModEngine is a complete IFPEN 1 library, resulting f rom our participation in those European projects. It allows the modelling of a complete engine with diesel and gasoline combustion models. It may be interfaced with control algorithms written in Simulink thanks to the new Functional Mock-up Interface specification from Modelisar project. Both versions under commercial software Dymola and free one OpenModelica are available. Feedback will concerns also problems encountered and advantages in use Dymola and OpenModelica platforms.
