Abstract
This study mainly explores the evolution in the subject development of artificial intelligence documents in the field of automation and control systems from 1956 to 2019. Based on the search in WoS SCIE database, 27,782 documents are revealed. The VOSviewer is then employed to draw the co-citation network diagram. Moreover, both VOSviewer and Citespace are used to draw the keyword co-occurrence network diagram and the burst word change diagram from 2000 to 2019 to master the field trend. The results from the keyword co-occurrence reveal that “neural network” and “adaptive control” are the main keywords in all periods and after 2010 , the research topics has shifted to “adaptive control”, especially in Lyapunov method, nonlinear control system, control system synthesis and multi-agent system. The overall document co-citation network can be roughly divided into two research axes: “adaptive control” and “nonlinear system”. In terms of author cocitation, Ge, Shuzhi Sam, Li, Zhijun, He, Wei are the most commonly cited high-productivity authors, while Lewis, Frank L. is at the center of the whole co-citation network and plays a leading role in the field. In terms of journal co-citation, Automatica and IEEE Transactions on Automatic Control are most often cited together with other journals, and the link strength between the two is strong. These two journals are of small number but high-quality publications. IEEE Transactions on Industrial Electronics is at the center of the co-citation network, which shows its multidisciplinary nature.
