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模态下工作过程,建立了交流小信号模型,得出控制变量到状态变量的传递函数,在此基础上设计了R-S-T控制器并对其进行参数整定.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,最后通过仿真和实验验证了此方案的正确性和可行性.
In order to improve the the dynamic characteristics of the hybrid power bi-directional DC/DC converter in the working process,a kind of R-S-T control strategy used for three-channel staggered parallel bidirectional Buck/Boost converter is presented.The working process in the Buck mode is analysised and alternating Current small signal model is established.The controller corresponds to buck working mode is designed and the paramete is adjusted.Compared with the traditional control of PI control,the R-S-T control strategy has better dynamic response characteristics and steady state response characteristics.At last,through simulation and experiment verified the correctness and feasibility of this scheme.
