Abstract: |
This
paper presents an efficient simulation scheme for hybrid systems modeled as
hybrid bond graphs (HBGs). Considerable
computational savings are achieved when mode changes occur during simulation
by identifying persistent causal assignments to bonds, and, conse- quently, fixed causal
structures at HBG junctions when the simulation model is derived. Persistent
causal assign- ments also reduce the possible
computational structures across all mode changes, and this leads to an overall
re- duction in the complexity of the simulation
models. We demonstrate the benefits of our approach for an electrical power
distribution system that includes a fast switching inverter system. |
