研究了高阶线性时不变广义群系统的容许一致性分析和一致性控制器设计问题。首先,通过将奇异群体系统的状态投影到一致性子空间和互补一致性子空间,以线性矩阵不等式的形式给出了一致性可容许的充要条件。提出了一种降低计算复杂度的方法,该方法只需要检查3个与代理数量无关的LMI。然后,利用变变量方法,给出了合意可容许的充分条件。给出了一致性函数的显式表达式,并证明了如果每个智能体是R-可控的和脉冲可控的,并且交互拓扑有生成树,则一致性函数的模式可以任意放置。最后,将理论结果应用于多智能体支撑系统的协同控制问题。
Admissible consensus analysis and consensualizing controller design problems for high-order linear time-invariant singular swarm systems are investigated. Firstly, by projecting the state of a singular swarm system onto a consensus subspace and a complement consensus subspace, a necessary and sufficient condition for admissible consensus is presented in terms of linear matrix inequalities (LMIs). An approach to decrease the calculation complexity is proposed, by which only three LMIs independent of the number of agents need to be checked. Then, by using the changing variable method, sufficient conditions for admissible consensualization are shown. An explicit expression of the consensus function is given, and it is shown that the modes of the consensus function can be arbitrarily placed if each agent is R-controllable and impulse controllable and the interaction topology has a spanning tree. Finally, theoretical results are applied to deal with cooperative control problems of multi-agent supporting systems.
