Distributed fixed time adaptive cooperative tracking control for quadrotor unmanned aerial vehicle
This research introduces a novel distributed fixed-time adaptive control scheme for quadrotor UAV formations, addressing challenges in communication-constrained environments. Unlike traditional methods, it guarantees convergence within a predefined time, independent of initial conditions. Key innovations include a distributed fixed-time observer for accurate leader state estimation and a fuzzy adaptive nonsingular terminal sliding mode controller for robust position tracking. An efficient indirect fuzzy identification mechanism reduces computational load. Simulation results confirm its effectiveness, speed, and robustness for UAV formation control.
