Robust H 2 Consensus for Multi-Agent Systems With Parametric Uncertainties
TLDR
The robust consensus problem of linear multi-agent systems in the presence of parametric uncertainties and noise signals is defined and the design procedure for the distributed state feedback controller is developed to synchronize the network.Abstract:
This brief is concerned with the robust $H_{2}$ consensus problem of linear multi-agent systems in the presence of parametric uncertainties and noise signals. The robust $H_{2}$ consensus problem is defined and the design procedure for the distributed state feedback controller is developed to synchronize the network as well as guarantee a prescribed $H_{2}$ performance. As s special case, the robust consensus problem with only parametric uncertainties is also studied and is converted into the simultaneous $H_{\infty }$ stabilization problems for a set of subsystems. The controller parameters are determined by solving some linear matrix inequalities.read more
