Description: |
This paper proposes a distributed fault-tolerant cooperative control framework for multiple fixed-wing UAVs (FUAVs), grounded on a complete six-degrees-of-freedom (6-DOF) nonlinear dynamic model. The architecture integrates position and attitude control, explicitly accounting for actuator faults and multiple input constraints. In the outer loop, an adaptive proportional-derivative (PD) controller is implemented, with its gains optimized online via a model predictive control (MPC) strategy to handle time-varying constraints. The inner loop incorporates a fixed-time extended state observer (ESO) to estimate uncertainties and actuator degradation, combined with an online optimization mechanism to enforce actuator limits and enhance fault resilience. Uniform ultimate boundedness of tracking errors is formally guaranteed through Lyapunov analysis. Hardware-in-the-loop (HIL) simulations on a Pixhawk 6C autopilot, along with comparative studies against representative control strategies, demonstrate the proposed scheme's real-time feasibility and strong robustness under actuator faults and multiple input constraints. |
