本文介绍了各种方法，提高整体估计质量的类扩展状态观测器（ESO），它不仅估计系统的常规状态，但作为干扰。这类观测器是形成自抗扰控制结构（ADRC）的关键，其中在线扰动重构和消除的精度直接影响闭环控制系统的鲁棒性。本文介绍了基于观测器的扰动估计/抑制回路的各个方面，并将其分为三类，与观测器相关：结构、调谐和工作条件。该调查致力于研究人员和从业人员谁有兴趣提高其基于ADRC的管理计划的效率。(C)2015年伊萨。由爱思唯尔有限公司出版。保留所有权利。
This survey presents various methods of improving the overall estimation quality in the class of extended state observers (ESO), which estimate not only the conventional states of the system, but the acting disturbance as well. This type of observers is crucial in forming the active disturbance rejection control structure (ADRC), where the precision of online perturbation reconstruction and cancellation directly influences the robustness of the closed-loop control system. Various aspects of the observer-based disturbance estimation/rejection loop are covered by this work and divided into three categories, related with observer: structure, tuning, and working conditions. The survey is dedicated to researchers and practitioners who are interested in increasing the efficiency of their ADRC-based governing schemes. (C) 2015 ISA. Published by Elsevier Ltd.
