ABSTRACT This paper addresses the prescribed‐time optimized formation tracking control problem for unmanned aerial vehicles (UAVs) while considering collision avoidance. The UAV system is divided into two parts: The position subsystem and the attitude subsystem. To achieve prescribed‐time convergence with adjustable accuracy, we develop a novel time‐varying transformation function that incorporates both the specified convergence time and desired precision parameters. For collision‐free formation maintenance, a modified barrier Lyapunov function is constructed to simultaneously enforce performance constraints and prevent inter‐agent collisions. The control architecture is enhanced through an innovative reinforcement learning (RL) strategy, where a fuzzy logic system (FLS)‐based actor‐critic structure is employed to approximate the optimal control policy by solving the derived Hamilton‐Jacobi‐Bellman (HJB) equations. The proposed algorithms are validated by simulation.
