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...
In this paper, a discrete-time flatness-based control for a twin rotor aerodynamic system with two degrees of freedom is proposed that outperforms a standard quasi-continuous implementation, cf. [1]. A control-oriented state-space model is derived using Lagrange's equations. The resulting nonlinear fourth-order model possesses two control inputs, and is affected by two unknown disturbance torques...
