直流微电网中Boost变换器的变阶次分数阶滑模控制
摘要:针对直流微电网中Boost电力电子变换器负荷侧波动频繁问题，设计一种新型变阶次分数阶非奇异终端滑模控制(variable order fractional-order non-singular terminal sliding mode control, VO-FNTSMC)策略，对负荷扰动进行精准快速的响应。主要研究该控制策略在Boost变换器启动阶段及负载变化阶段的控制效果，并将研究结果在NI PXIe-ModelingTech实验平台上以硬件在环(hardware in loop, HiL)的方式进行实验验证。结果表明：普通分数阶控制策略在分数阶微积分阶次为1时，具有抖振和输出误差较小的优势；在阶次为1.4时，具有超调量小、响应快速的优点。VO-FNTSMC融合了2个不同阶次分数阶控制器的优点，在启动阶段及负载变化阶段对输出电压都具有更快的响应速度，更小的超调量、稳态误差及滑模抖振，为分数阶控制理论应用于新能源电力电子领域提供了一种深入到变阶次的研究方法。

Abstract：To solve the problem of frequent fluctuations on the load side of power electronic Boost converter in DC microgrid, a novel variable order fractional-order non-singular terminal sliding mode control strategy (VO-FNTSMC) is designed to accurately and quickly respond to the disturbance. The control effect of the control strategy in the start-up phase and load change phase of the Boost converter is studied. The research results are experimentally verified by hardware in loop (HiL) method on the NI PXie-ModelingTech experimental platform. The results show that the general fractional control strategy has the advantages of smaller chattering and output error when the order of fractional calculus is 1; When the order is 1.4, it has the advantages of small overshoot and fast response. VO-FNTSMC integrates the advantages of the above two orders of fractional control, and has faster response speed, smaller overshoot, steady-state error and sliding mode chatter to the output voltage in the start-up stage and load change stage, and it has the advantage of fractional controller in different order regulation effect. It provides a deep research method of variable order for the application of fractional order control theory in the field of new energy power electronics.
