摘要
Abstract
Bidirectional full-bridge DC-DC converter is widely used in power bidirectional flow systems, especially in electric vehicles and renewable energy generation. Firstly ,on the basis of the single phase shifting control model of bidirectional full bridge,the discrete small-signal model of bidirectional full-bridge converter was established with the method of discrete sampling and modeling. Secondly,the state-feedback integral control system with zero steady-state error was designed,in which the desired closed-loop pole position was set up to achieve the step-output response with none-overshoot and the high-efficiency of the digital closed-loop controller is verified by simulation. Lastly,the susceptibility of the state-feedback coefficient matrix to the main parameters of the converter is analyzed. Besides,under the same feedback coefficient matrix,the transient response of different system parameters is proved.关键词
