Then a DC-motor servo system is modeled and simulated using 20-sim software, and a LQG controller is also designed. It indicates that modeling using bond graph is concise and easy, its parameters are also related the physics components directly, and it is an appropriate diagram approach for modeling mult-i domain mechanical and electronic systems. It can be broadly applied to modeling and simulation of mult-i domain mechanical and electronic systems.
