In this paper, we explore a novel modeling technique to investigate a parafoil flying in wind environments by using computational fluid dynamics. Further, we apply an eight-degree-of-freedom dynamic model of the parafoil in wind environment based on utilizing revised aerodynamic equations. Given that the traditional control methods cannot always tackle trajectory tracking effects properly, we propose...
Because of the remarkable non-linearity, large inertia and strong atmospheric disturbances, traditional control methods cannot ensure the trajectory tracking control performance for a parafoil airdrop robot. In this sense, we propose a trajectory tracking control method based on active disturbance rejection control. Then the proposed control method is evaluated by simulation and airdrop experiment...
The simulation of shipboard firefighting is very difficult, since it is hard to quantitatively analyze and describe the behavior of all elements involved. A Multi-Agent based shipboard firefighting model has been presented in this paper. The architecture and cooperation mechanism of the agents are discussed in some detail.
