本技术说明关注连续时间和离散时间多智能体系统(MAS)的输出反馈一致性,其特征在于具有定向通信拓扑的高阶线性系统。基于降维观测器的分布式协议仅利用相邻代理的相对输出和输入。结果表明,所提出的输出反馈协议的一致性是等价的状态反馈协议的一致性。在MAS的开环动力学不是指数不稳定的条件下,建立了一种只利用相邻Agent相对输出的截断降维观测器协议.最后通过数值算例说明了所提方法的有效性。
This technical note is concerned with output feedback consensus of both continuous-time and discrete-time multi-agent systems (MASs) characterized by high-order linear systems with directed communication topologies. Distributed reduced-order observer based protocols are established by only using the relative outputs and inputs of neighboring agents. It is shown that consensusability by the proposed output feedback protocols is equivalent to the consensusability by state feedback protocol. Under the condition that the open-loop dynamics of the MASs is not exponentially unstable, a truncated reduced-order observer based protocol utilizing only the relative outputs of neighboring agents is also established. A numerical example is given to illustrate the effectiveness of the proposed approaches.
