| Abstract: | Port-controlled Hamiltonian systems and passivity-based control theory was applied to a Buck converter with constant power load. A Hamiltonian modeling of the buck converter was established and then analyzed for the stability of the equilibrium. The feedback controller was also designed. The simulation results show that control system has a good dynamic and steady state performance through adjusting controller parameters. |
