Active leader tracking control of multi-agent systems with quantized measurements

This paper discusses tracking control problem with a discrete-time multi-agent system with active leader and quantized communication constraints. For the active leader in a general linear form, we give a distributed design for each discrete-time agent in the leader tracking control problem and analyze the tracking convergence with the help of Riccati equation and common Lyapunov function when the communication channel is perfect. Then a stochastic quantization strategy is applied to model the information transmission in the agent coordination and the corresponding solution is also given, even if the interconnection topology is switching.
