基于干扰观测器的控制（DOBC）及相关方法在过去四十年中已在各个工业领域得到研究和应用。本综述首次对现有的干扰/不确定性估计和衰减技术进行了系统而全面的介绍和总结，其中最显著的是DOBC、自抗扰控制、干扰适应控制以及复合分层抗干扰控制。在所有这些方法中，干扰和不确定性通常被集中在一起，并且采用一种观测机制来估计总干扰。本文首先回顾了一些广泛使用的线性和非线性干扰/不确定性估计技术，然后讨论并比较了各种补偿技术以及将干扰/不确定性补偿与（预先设计的）线性/非线性控制器集成的过程。它还对该领域的主要方法提供了简洁的教程，并清晰地描述了它们的特点。综述了这组方法在各个工业部门的应用，重点介绍了一些算法的商业化情况。最后讨论了未来的发展方向。
Disturbance-observer-based control (DOBC) and related methods have been researched and applied in various industrial sectors in the last four decades. This survey, at first time, gives a systematic and comprehensive tutorial and summary on the existing disturbance/uncertainty estimation and attenuation techniques, most notably, DOBC, active disturbance rejection control, disturbance accommodation control, and composite hierarchical antidisturbance control. In all of these methods, disturbance and uncertainty are, in general, lumped together, and an observation mechanism is employed to estimate the total disturbance. This paper first reviews a number of widely used linear and nonlinear disturbance/uncertainty estimation techniques and then discusses and compares various compensation techniques and the procedures of integrating disturbance/uncertainty compensation with a (predesigned) linear/nonlinear controller. It also provides concise tutorials of the main methods in this area with clear descriptions of their features. The application of this group ofmethods in various industrial sections is reviewed, with emphasis on the commercialization of some algorithms. The survey is ended with the discussion of future directions.
