摘要：
A novel energy-shaping controller design technique is applied to the output voltage control of DC/DC converter. Based on the average dynamic model of the power converter, the port-controlled Hamiltonian (PCH) model of DC/DC converter is established. The passive control scheme of DC/DC converter is presented assigning a storage function with a minimum at the desired equilibrium. The controller is designed based on the interconnection and damping matrix assignment. The closed-loop energy function can be used as Lyapunov (or storage) function rendering more transparent the stability analysis. The PCH structure of the system is preserved in closed-loop. The simulation results show that the proposed scheme has a good performance and practical application prospect.
