# 2D Taut Cable Control Of Tethered UAV ReadME ###### tags: `Github README` Implementation of the paper [Taut Cable Control of a Tethered UAV](https://folk.ntnu.no/skoge/prost/proceedings/ifac2014/media/files/2581.pdf) by Marco Nicotra et al. This paper looks into the case where the actuated winch controls the length of the rope while the UAV is in charge of keeping it taut. ![](https://i.imgur.com/aq3krNg.png =300x400) ### Assumptions - The string is massless, inextensible and attached to the centre of mass of the UAV - The cable is taut throughout the process $T(t) > 0 \hspace{0.5cm} \forall t \geq0$ $T(t) = T(r(t),\alpha(t),\theta(t) \hspace{0.3cm}is$ $T = mr\dot{\alpha}^{2} -mgsin\alpha + sin(\alpha + \theta)u_1 - m\ddot{r}$ ### Dynamics Under these two assumptions, dynamics of UAV can be formulated as: ![](https://i.imgur.com/U3FFRdW.png) ### Control Objectives ![](https://i.imgur.com/avk2Zdp.png) ### Control Architecture ![](https://i.imgur.com/Zme3Geb.png) ### Results ![](https://i.imgur.com/K3RbinH.png) ![](https://i.imgur.com/pLg130m.png) ![](https://i.imgur.com/GX4PoZT.png) ![](https://i.imgur.com/vNRT51F.png) ![](https://i.imgur.com/Gx5SN9A.gif)
