Prescribed Performance Consensus of Heterogeneous Quantized High-Order Uncertain Multi-Agent Systems

Abstract We consider the problem of guaranteeing output consensus, with prescribed transient and steady-state performance bounds, for a class of uncertain, heterogeneous, high-order, nonlinear multi-agent systems, in a leader-following scheme. The proposed control protocol is decentralized and of low-complexity. An interesting feature is that information (state measurements, control inputs) is exchanged only in quantized form. For that purpose, uniform-hysteric quantizers are utilized. Simulations illustrate the effectiveness of the approach.
