Designing mechatronic systems, a model-based perspective, an attempt to achieve SysML-Matlab/Simulink model integration

Abstract

Higher demands on efficiency, cost and functionality have contributed a great deal towards the advent of Mechatronic systems where mechanics, electronics and computer software integrate together to provide the required functionality. This integration has its effects in the design process as well, and a good design requires careful integration of methods and tools to satisfy the overlapping objectives. The set of requirements a designer needs to satisfy for a good design are in all three domains, hence various design and modelling tools are used by engineers to satisfy these multi-domain requirements. With the advent of systems modelling languages for specifying the complete system in one system model, there is an increased urge to link the system modelling tools to the domain specific tools such as Matlab/Simulink. In this paper we present an attempt to achieve an integrated design environment by building mapping between SysML and Matlab/Simulink models. The complexities that can be solved using SysML and the ones which necessitate a communication between SysML and other tools are discussed. Models of an industrial pattern generator are presented to explain the practical influence of this integration approach. The resulting integrated model is more comprehensive for the designer when investigating various design alternatives. This is important for companies considering they have to consistently embed innovation and sustainability in their products.
