報告摘要: In many applications, a network of autonomous agents holds eminent promises to achieve a desired level of performance, capability, robustness, and efficiency beyond what a single agent can achieve. However, to be advantageous, multiple agents have to work in an coordinated and synchronized manner. This talk considers a network of agents (or sub-systems) and seeks a distributed algorithm to steer the agents so that a global objective is achieved. Three distributed optimization problems will be discussed, namely, distributed estimation, distributed control and distributed localization. Firstly, we will study the weighted least squares (WLS) estimation problem for a networked system and offer a fully distributed algorithm for optimal WLS estimation. This algorithm is then extended to distributed average consensus and distributed Kalman filtering for networked systems. Secondly, we will investigate the formation control for a networked multi-agent systems. We will present a new approach for 2-dimensional and higher dimensional formation. A necessary and sufficient condition will be given in terms of a new type of graph connectedness, called rooted connectivity. A linear distributed control law will be provided using relative position measurements on the local frames attached to the agents. Finally, we will study distributed localization problems for a network of sensors where relative measurements and information exchange between neighbouring sensors are used to determine the physical locations of individual sensors. Several distributed solutions will be discussed.
