Bond Graph Modeling and Simulation of Dynamically Tuned Gyroscope

Bond graphs provide a useful notation for the purpose of modeling physical systems. This paper models the open loop system of a Dynamically Tuned Gyroscope (DTG) using bond graph according to its structure, and performs the simulation of the model using 20-sim software. The simulation results are identical with the Matlab simulation results of open loop transfer function of DTG, which proves that the bond graph model of DTG is valid. This paper constructs the basis of the whole mechatronic system bond graph modeling of DTG, it's helpful for the design of digital rebalance loop, and can be used for the integrative design and simulation of structure and control..
