Conversion script from 1.1 provided.
Version 1.1 is a major update of the Engine Dyamics Library.
Several new components have been added to facilitate creation of engine system model with very few states. Such models may be desirable in order to improve simulation speed of desktop simulations and SIL applications, and are suitable to linearize in case the model should be used for model based control system development. The new components created for this purpose are:
In addition to this, these new components have also been added:
fuel_flow_min= 0 and providing zero inlet fuel flow, the equation for the excess air factor
lambdawould result in division by zero. This has been fixed by limiting the denominator by Modelica.Constants.eps.
Some classes have moved in the library structure or changed name since version 1.0 of EDL. The provided conversion script can perform all required conversions of user models.
Engine Dynamics 1.1 is based on the Modelon Base Library 1.8
This is the first official release of the Engine Dynamics Library.
Engine Dynamics Library (EDL) provides a framework for combustion engine system modeling, simulation and analysis, including the complete air gas exchange. The library is well suited to represent transient engine response and related engine control. Applications include control design with the purpose of transient engine out emissions reduction, transient exhaust condition modeling for optimum EATS operation conditions, and engine response dynamics.
EDL utilizes a mean value combustion model for torque, charge flow and exhaust condition modeling. Pressure and thermal dynamics of the complete air gas exchange process can be studied. Several turbo charger and EGR configurations can be modeled, including variable geometry turbine designs.
Highlight features of the library are:
Engine Dynamics 1.0 is based on the Modelon base library 1.7.
