Consensus disturbance rejection over uncertain networks
Miao Liu, Zhongkui Li · 2017
This paper deals with the consensus disturbance rejection problem for networked systems coordinating over uncertain communication channels. Each communication channel of the network is modeled as an ideal transmission system with the unitary transfer function perturbed by a norm-bounded uncertainty, which is particularly susceptible to describe quantization errors and communication noises. A distributed disturbance observer is designed for each agent to estimate the disturbance, based on which an observer-based consensus protocol is proposed by utilizing the uncertain relative state information among neighboring agents. Sufficient conditions in terms of linear matrix inequalities are further derived to design the protocol.
