摘要
文章提出了一种基于自抗扰控制的微电网负载接口变换器控制策略。通过设计改进型控制器,结合跟踪微分器、扩张状态观测器和非线性反馈控制,有效补偿不确定因素和外界干扰,提升了系统鲁棒性。仿真和实验结果表明,与传统PI控制相比,新策略具有更快响应、更小误差和更强抗干扰能力,为微电网控制提供了新思路。
This paper proposes a microgrid load interface converter control strategy based on self-disturbance rejection control.By designing an improved controller that integrates tracking differentiators,extended state observers,and nonlinear feedback control,the proposed approach effectively compensates for uncertainties and external disturbances while enhancing system robustness.Simulation and experimental results demonstrate that compared with traditional PI control,the new strategy exhibits faster response,reduced error,and stronger anti-interference capabilities,providing innovative solutions for microgrid control.
