Engineers practicing model based system design in an automotive sub-system supplier often use Modelica for modeling physical plant models and MATLAB/Simulink® for modeling the controller. Model-in-loop (MIL) simulations are performed using the S-function generated from the chosen Modelica plant model; integrated with the appropriate controller model and then simulated in Simulink. These steps are carried out by the engineer manually for the many different plant-controller configurations available in the organization. This repetitive workflow provides significant opportunities to streamline and automate the model based development process and improve productivity.
This paper presents an in-house MATLAB® GUI tool that can be used to configure the plant; select the controller; automatically generate an integrated model with the plant and controller; and simulate the resulting model. The plant model configuration information is passed on to Dymola® (the simulation environment) using the available communication (COM or DDE) to generate the plant model S-function. This tool includes post processing capabilities such as plotting the simulation results and custom plotting of metrics that are generated postsimulation.
