Dynamic Analysis of Bidirectional Multi-Input DC-DC Converter Based on Nonlinear Control by IOFL

This paper presents a dynamic nonlinear model for Bidirectional Multi-Input DC-DC Converter. A dynamic converter model is proposed as a nonlinear multiple input and one-output converter, so that feedback linearization can be directly utilized. And it is compared with linear control in this paper. During the control design, phase shift is defined as the control variable, and the output voltage is appropriately defined as the control objectives. The details of the design of the control scheme are provided in the paper. The proposed dynamic model was tested by the simulation results. The simulation results show that nonlinear control has good performance.
