Recent developments on controllability of multi-agent systems

Controllability is a fundamental research issue in the study of cooperative control of multi-agent systems. This paper presents an overview on the state-of-the-art of the controllability of multi-agent systems. Some basic issues in the field of controllability of multi-agent systems are introduced, and the research hotspots and frontiers are analyzed and summarized from the perspective of interconnection topology. Furthermore, some of the latest research achievements on structural controllability are presented, and some related problems such as observability, stabilizability and controllability of complex networks are also introduced. Finally, the existing problems to be solved and the possible research direction are summarized.
