Abstract:A variable-structure approach for Modelica models is presented in this paper. Variable structure models enable the user to change the simulation model during runtime. This is not supported by common simulation environments and thus a Matlab script is used to control the run of the simulation. The script switches between the different models and sets the initial values to ensure smooth transients of the variables. The method is applied to a model of a thermal management system for Lithium ion batteries in a hybrid vehicle. In this model some components don not need to be calculated through the complete simulation time and are removed from the model through the variable-structure approach. With this approach the simulation time can be reduces while the simulation accuracy is not affected negatively
