| 摘 要： | 为了提高复合电源双向DC/DC变换器工作过程中的动态特性,提出一种用于三通道交错并联双向Buck/Boost变换器的R-S-T控制策略。分析该变换器在Buck/Boost模态下工作过程,建立了交流小信号模型并得出控制变量到状态变量的传递函数,在此基础上设计了双向DC/DC变换器的R-S-T控制系统。相较于传统的PI控制,R-S-T控制策略具有更好的动态和稳态响应特性,最后运用Matlab/Simulink软件对该变换器系统进行仿真。结果表明,基于R-S-T控制的复合电源双向DC/DC变换器具有响应速度更快,超调量更小,鲁棒性更强的特点。

| Abstract: | In order to improve the working process in dynamic performance of the hybrid power bi-directional DC/DC converter, R-S-T control strategy is put forward for three-channel staggered parallel bi-directional Buck/Boost converter. The working process of converter in Buck/Boost mode is analyzed by magnetic integration theory, AC small signal model is established and the transfer function from control variables to the state variables is obtained, based on which the R-S-T control system of bi-directional DC/DC converter is designed. Compared to traditional PI control method, R-S-T control strategy has better dynamic and steady-state response characteristics in controling three-channel staggered parallel bidirectional converter. Finally, the converter system is simulated by using Matlat/Simulink software. The simulation results show that the hybrid power bi-directional DC/DC converter based on R-S-T control has faster response speed, smaller overshoot volume, and stronger robustness. |
