摘要

针对直流母线电压的控制性能受到各种不确定干扰因素负面影响的问题,提出一种改进型自抗扰控制策略以增强直流母线电压的控制稳定性。该策略采用级联扩张状态观测器来补充传统方法下未估计的剩余扰动,进而提升扰动估计抑制能力。最后,通过理论分析和仿真结果验证所提策略的有效性和可行性。

Abstract

Aiming at the problem that the control performance of the DC bus voltage is negatively affected, an improved active disturbance rejection control （ADRC） strategy is proposed to enhance the control stability of the DC-link voltage. The cascaded extended state observer is employed to supple the residual disturbance that is not estimated under the traditional method, thereby improving the disturbance estimation ability. Finally, the effectiveness and feasibility of the proposed strategy are verified by theoretical analysis and simulation results.
