摘要

针对交错并联变换器动态跟踪时间较长和负载扰动时存在二次振荡的问题，提出1种变带宽自抗扰控制策略。首先基于小信号模型分析，将寄生参数摄动的影响计入传递函数中，以消除寄生参数引起的内部不确定性扰动；接着从频域特性入手，在稳定性和抗扰特性方面分析带宽与抗干扰能力的影响关系；最后利用蒙特卡洛实验对所提策略进行鲁棒性检验。通过仿真和实验结果可见，所提策略在目标值跟踪和抗扰品质方面均优于双闭环比例积分PI（proportional-integral）控制，提高了系统动态性能和抗扰能力。

Abstract

Aimed at the issues of a long dynamic tracking time and secondary oscillation during load disturbances in interleaved parallel converters, a variable bandwidth active disturbance rejection control strategy is proposed. First, based on the small-signal model analysis, the influence of parasitic parameter perturbations is taken into account in the transfer function, so as to eliminate internal uncertainty disturbances caused by parasitic parameters. Then, starting from the frequency-domain characteristics, the relationship between bandwidth and anti-interference capability is analyzed in terms of stability and anti-interference characteristics. Finally, Monte Carlo experiments were used to test the robustness of the proposed strategy. Simulation and experimental results show that the proposed strategy is superior to double closed-loop proportional-integral (PI) control in target value tracking and anti-interference quality, thus improving the system’s dynamic performance and anti-interference capability.
