Modeling, identification and simulation of mechatronic systems

摘要: ABSTRACT The integration of mechanical and microelectronic components during the design operation requires systematic methods software tools for theoretical modeling, experimental identification simulation. Therefore, contribution summarizes state-of-the-art in these areas based on practical experience with several mechatronic systems tries to show open problems. It is typical that they are composed from different physical domains, such as electrical mechanical, fluidic, thermal thermodynamic processes. One key issues, therefore, find a unified way especially but also simulation heterogeneous systems. A further task develop make them interconnectable. For modeling procedure can be given lumped parameter processes energy material flows. multi port representation stated flows electrical, fluidic However, problems arise development ports block diagrams bond graphs shortly described. Present developments characterized by object-oriented introduction causalities at late state. Identification required frequently e.g. model verification or on-line estimation unknown time varying parameters nonlinear static characteristics dynamics. properties suitable described, including dynamical neural networks Then, various kinds regard behaviour. applications real-time required. Examples process hardware-in-the-loop together real control components, controller prototyping. Application examples shown throughout paper, an turbocharger combustion engine.
