Formation Configuration for Cooperative Multiple UAV via Backstepping PID Controller

摘要

The issue of formation rearrangement for a troop of cooperative unmanned vertical takeoff and landing (VTOL) aircrafts in an obstacle-loaded atmosphere is figured out using a purposed backstepping based proportional-integral-derivative controller (PID). The designed controller is developed to regulate every unmanned quadrotor within the troop in an exceedingly localized manner guaranteeing the reserving of the required geometric formation. The backstepping technique could be a promising control technique for nonlinear and coupled multivariable systems. The essential contribution in this paper concentrates on resolving the formation issue for a troop of cooperative pilotless VTOL airplanes in a decentralized manner via backstepping PID regulator. The designed decentralized controller guarantees the success of the required mission of the swarming troop. The simulation results declare the successes of the proposed controller in guaranteeing the stability of the system and reserving of the desired geometric formation either within the existence or absence of obstacles.
