In this paper, a second-order fully actuated system model is derived for a six degree of freedom aircraft model with control coupling. Then a three channel joint optimal attitude control method of roll, yaw and pitch is designed on high-order fully actuated system theory. Through mathematical simulation of this controller and the traditional PID controller, it is shown that the PID control method has a great shortage in the aircraft with control coupling, and the fully actuated system theory control method can well solve the problem of aircraft coupling, achieve the stable tracking of aircraft attitude command, and has better rapidity.
A decoupled control approach based on linear active disturbance rejection control idea is proposed. The plant model, in which the coupling dynamics is as a part of disturbance, is established, and some virtual control...

This paper proposes a cooperative path-planning method based on multi-Dubins path segments to meet the penetration requirements of UAVs in a complex threat environment. A pruning strategy is used in path-planning to sift path segments, and the diversity of threat avoidance paths is considered under a reasonable calculation amount. A threat intrusion strategy is designed for no safety path condition, which makes the cooperative path-planning method have excellent robustness. A cooperative path optimization method based on particle swarm optimization is adopted for the path length and collision avoidance *** simulation results show that the UAV cooperative paths can avoid the threat area under any starting and ending points, and path lengths are close to the expected length.
This paper considers the energy-constrained multi-UAV multi-area coverage path planning problem which is a generic technology backbone of many survey applications using multiple UAVs. The problem is usually NP-hard an...
