• A coupled PDE mathematical model of two-deformation flexible wing is established. • Did not simplify the infinite-dimensional PDE model to an ODE model. • Consensus strategy for multi-agent systems was designed based on the PDE model. • Vibration control is simultaneously considered and the vibration is suppressed. Modeling and consensus control of flexible wings with bending deformation and torsion deformation are studied in this paper. Due to the physical properties of flexible materials, vibration suppression of the flexible wings is also considered in addition to consensus control. Different from most of the published work of multi-agent control theory, the agent system studied in this paper is a distributed parameter system. Considering the mutual coupling of the wing's bending deformation, torsion deformation and the rotation angle of the root joint, the dynamics model of each agent can be expressed by a set of partial differential equations (PDEs) and ordinary differential equations (ODEs). Boundary control algorithms are designed to achieve control objectives. It is proved that the states of all agents are consistent and the closed-loop system is asymptotically stable. Finally, numerical simulation is carried out to demonstrate the effectiveness of the proposed control scheme. [ABSTRACT FROM AUTHOR]
