We are concerned with a multi-agent system, which contains centripetal force, inter-particle bonding force, and velocity-alignment operator. In particular, we employ a regularized rotation operator to overcome the singularity problem at antipodal points. In this talk, we introduce several control laws for given tasks, such as target tracking or formation. Using these control laws, we observe the asymptotic behavior of agents: complete or practical synchronization. Our numerical simulations show that it is applicable to reality. The presented results come from a series of work with S.-H. Choi and D. Kwon. 4. 16:00 – 17:30 - 발표자: 최선호 교수(경희대학교) - 주제: MULTI-AGENT SYSTEMS USING BEARING ANGLES AND ANCHOR POINTS - 초록: We propose a bearing-based control law for double-integrator multi-agent systems. The objective is that each agent converges towards a predefined point. Since bearing angles alone cannot determine a unique formation, at least three anchor points are required. The leader agents are those converging towards these anchor points. These leader agents have access to the location information of the anchor points, their own location information, and the bearing angles of surrounding agents. We assume that all other agents can only collect bearing angle information from neighboring agents. Like most bearing-based models, our model includes singularities, preventing the use of LaSalle’s invariance principle. To overcome this, we introduce a new energy functional. Using this energy functional and Barbalat’s lemma, we prove that all global solutions of this equation converge to the specified formation. ### 현장 강의만 진행될 예정입니다.
