Abstract: Aiming at the logical structure model, logical/physical behavioral models and principle scheme presentations for mechatronic systems on the principle design stage, reference model was applied to represent the initial logical structure and unified modeling language（UML） diagrams to represent the detail logical structure (i.e. principle scheme presentation) of a mechatronic system. message sequence charts（MSC） were applied to expound the interaction between systems and specification and description language（SDL） charts to simulate overall (logical and physical) system behaviors. A new perspective was thereby presented on the objectoriented design and analysis for mechatronic systems based on the way of human cognition for the objective world. As an example, the system structure and behaviors of a CD player were illustrated in detail. The results indicate the effectiveness of the objectoriented system modeling method.
