Скачать или смотреть Bond Graphs: A Universal Language for Engineering Systems

The source introduces the concept of bond graphs as a revolutionary, unified language for modeling complex physical systems that incorporate multiple domains, such as electrical, mechanical, and hydraulic components. This method is crucial because traditional engineering approaches required separate, isolated models for each physical domain, which failed to capture the complete, interconnected picture of modern hybrid machines like cars. Bond graphs overcome this by focusing entirely on the flow and manipulation of energy as the common denominator among all components, resulting in a single, coherent blueprint. The primary advantage of this unified model is its application in structural analysis, allowing engineers to assess fundamental stability, controllability, and observability of a system early in the design phase. Finally, this energy-based framework facilitates the design of smarter systems by optimizing sensor placement and enabling automatic fault detection and isolation.
