Consensus control is a research area in the field of control systems and robotics that focuses on achieving agreement among a group of interconnected systems or agents. The goal of consensus control is to design controllers that enable a group of agents to reach a common decision or state, even in the presence of disturbances, uncertainties, and communication delays. Applications of consensus control can be found in distributed robotic systems, sensor networks, and multi-agent systems. This research area combines principles from control theory, optimization, and communication networks to develop algorithms and strategies for achieving consensus in distributed systems.
