H2 suboptimal containment control of homogeneous and heterogeneous multi-agent systems
This paper deals with the H2 suboptimal state containment control problem for homogeneous linear multi-agent systems and the H2 suboptimal output containment control problem for heterogeneous linear multi-agent systems. For both problems, given multiple autonomous leaders and a number of followers, we introduce suitable performance outputs and an associated H2 cost functional, respectively. The aim is to design a distributed protocol by dynamic output feedback that achieves state/output containment control while the associated H2 cost is smaller than an a priori given upper bound. To this end, we first show that the H2 suboptimal state/output containment control problem can be equivalently transformed into H2 suboptimal control problems for a set of independent systems. Based on this, design methods are then provided to compute such distributed dynamic output feedback protocols. Simulation examples are provided to illustrate the performance of our proposed protocols.
