Design of mechatronic systems is driven by engineering efforts in multiple-domains, resulting in models developed in various formalisms. In spite of interconnections between these domains, approaches linking them theoretically are lacking. This lack of integration leads to major challenges in solving dependencies across different domains, slowing down the design process. In this paper, a model-level integration-framework is described, aiming to identify and solve dependencies across different domains during the design process of a mechatronic system. A two-degree of freedom robot example is presented, to exemplify the iterative process of design optimisation in a computer aided design tool (Solid Edge), connected with corresponding dynamic analysis and controller design in Matlab/Simulink. A system model built in systems modelling language (SysML) is extended to capture the cross- domain dependencies as parameters in a black-box model. These black-box models can be systematically linked with other domains (CAD and dynamic analysis) through the model integration algorithm (based on the robot example). As the modellers perform the design iterations in Matlab/Simulink and Solid Edge, the updates on cross-domain dependencies will be available through SysML model, containing the complete system view. Possible issues with un-identified dependencies (due to change in requirements), and their possible solutions are also discussed. It is emphasized that the robot example could be generalized towards mechatronic systems, along with the requirement specifications for the model-integration algorithm. It is demonstrated that efficient design solutions and reduction in design time are possible with concurrent multi-domain models integration.
