Abstract:

A distributed predefined time adaptive sliding mode control method is proposed to address the tracking control problem of a second-order fixed-wing Unmanned Aerial Vehicle (UAV) system with stochastic switching communication topology structure. Firstly, a three degree of freedom mathematical model for fixed-wing UAV cluster is established and transformed into a second-order integrator model with disturbances. Based on this established model, a suitable sliding surface is selected, and a distributed predefined time tracking controller is designed. To handle the interference problem faced by the UAV system during flight, an adaptive control strategy was proposed. In addition, this paper cites a predefined time theorem and proves through Lyapunov stability theory that the second-order UAV system can achieve stability within the predefined time. Finally, numerical simulations have demonstrated the feasibility of the proposed tracking control strategy for a fixed-wing UAV system with stochastic switching topology.

Key words: UAV, predefined time stability, distributed tracking control, sliding mode control, stochastic switching topology
