Input saturation: academic insights and future trends

Input saturation is very important for the analysis and design of control system. Ignoring the input saturation will have an adverse effect on the control system, and even cause the control system to be unstable. In practice, almost all the control systems are affected by input saturation, involving switched systems, multi-agent systems, robot systems and spacecraft rendezvous systems, etc. In the past few decades, a large number of research results have been obtained on input saturation. This paper attempts to give an overview through a bibliometric analysis based on the publications related to input saturation which were published from 2010 to 2020 and retrieved from the Science Citation Index Expanded database. We give a detailed discussion based on countries, institutions, research areas, journals, authors and author keywords. The main results show that Automatica takes the leading position among the top 10 academic journals, followed by International Journal of Robust and Nonlinear Control and IEEE Transactions on Automatic Control. China ranks a leading position in this field, followed by the United States and France. Harbin Institute of Technology has the topmost total articles, citations and h-index. The future research works are highlighted and we summarise the conclusion in end.
