Abstract:

CC Systems develops distributed embedded control systems for use in rough environments. During the development of a system's control software, simulations are used to test its functionality and to make the development process faster, more flexible, and independent of the control system hardware.

This thesis focuses on the dynamic models used in the simulations, and specifically on the modeling tools and methods used to build the models. The aim is to simplify the modeling process, and to improve the quality and applicability of the simulations by integrating a comercial modeling tool and CC Systems' existing simulation environment.

An evaluation of EASY5, Dymola, Simulink and SystemBuild shows that Simulink is the alternative that suits the present needs of CC Systems best. In order to make Simulink models fit properly into the existing simulation environment, required interfaces and functions are implemented. The resulting solution is tested and shows that it makes faster and more complex modeling than today possible. Simulink and the implemented interfaces perform satisfactorily.
