摘要：Research on cooperative multi-robot systems in the Advanced Control and Mechatronics lab will be introduced. Specifically, the presentation will focus on the consensus problem of a team of multiple quadcopter systems. Multiple-quadcopter systems have various civilian and military applications, such as forest fire monitoring and load transportation. However, since multiple-quadcopter systems are networked control systems (NCSs), they suffer from network-induced constraints, such as time delays and packet losses. Consensus, which is a basic coordination problem, is often desired for the group in achieving tasks. The objective of this work is to develop novel distributed consensus algorithms for multiple-quadcopter systems over two types of communication delays: uniform constant delays and asynchronous time-varying delays. The quadcopter system is simplified into four decoupled subsystems such that it can be studied in a multi-agent system (MAS) scale. The interactions among quadcopters are modeled using algebraic graph theory. The consensus problem is then converted to a stability analysis problem by defining the consensus error dynamics. Sufficient conditions for stabilizing controller design are developed based on Lyapunov's method and linear matrix inequality (LMI) techniques for both cases. Finally, extensive MATLAB simulations are carried out for both cases to verify the proposed algorithms. Discussions are given regarding the feasibility and effectiveness of the proposed controllers under various conditions. Real-time hardware implementation will be briefly discussed as well.
