A survey on optimal consensus of multi-agent systems

This paper provides a review of some main works and research progress in distributed optimal consensus problems of multi-agent systems. Classical and common methods in this area are summarized, such as Riccati design, adaptive dynamic programming and inverse optimal control. This paper detailedly addresses the design schemes of optimal consensus protocols by reviewing several typical literatures. Furthermore, the difficulties and challenges for solving distributed optimal consensus to multi-agent systems are pointed out and future research directions are also proposed.
