Abstract:

Trajectory tracking and time-varying formation control of unmanned aerial vehicle (UAV) swarm systems with switching interaction topologies are investigated. The UAV is modelled by a second-order integrator system. Based on the consensus method, protocols are proposed to transform the formation problem into a stability problem. The average dwell time of switching topologies is introduced, and an algorithm for the design of the gain matrix of the protocol is given by solving a linear matrix inequality (LMI). It is proven by constructing a piecewise continuous Lyapunov function that the trajectory tracking and time-varying formation can be achieved by the protocol proposed. Simulation of a swarm system consisting of four UAVs moving in the three dimensional space is conducted, and simulation results demonstrate that the trajectory tracking and time-varying formation for UAVs with switching topologies can be solved by the method proposed.
