摘　　要：基于多馈入直流系统的强非线性、强耦合特征,分析了多馈入直流系统对协调控制技术应用于工程实际的迫切需求,从线性和非线性控制、集中和分散控制等角度综述了多馈入直流系统协调控制技术发展过程及研究现状。首先,讨论了经典线性控制、非线性控制、最优控制、鲁棒控制、自适应控制等控制方法在多馈入直流系统协调控制中的应用。然后,针对多馈入直流系统集中协调控制方法需要反馈大量远方和不可测量信号存在的工程应用问题,阐述了近年来基于分散建模理论与关联测量、分布式闭环反馈、广域测量信号反馈等方法相结合的多直流分散协调控制研究成果。最后,探讨了协调控制应用于多馈入交直流系统所面临的重要问题和未来研究方向。Based on the strongly nonlinear and coupled characteristics of multi-infeed DC （MIDC） systems, this paper analyses the urgent requirements for the practical applications of coordinated control methods in real systems. From the perspective of linear/nonlinear control theories and centralized/decentralized control structures, the development process and the current research situation of the coordinated control technologies in MIDC systems are reviewed. First, application results of various coordinated control methods, such as classical linear control, nonlinear control, optimized control, robust control, adaptive control in MIDC systems, are discussed. Then, in view of the existing engineering application problems with the centralized coordinated control methods in MIDC systems that need remote and unmeasurable variables as feedbacks, this paper presents the research results of decentralized coordinated control methods in MIDC systems, which integrates the decentralized model theory with the correlative measured vectors, distributed closed-loop feedback and WAMS signals feedback methods. Finally, the problems and further research directions of the coordinated control methods in MIDC systems are also discussed.
