This paper addresses the robust control for a slung-mass quadrotor under abrupt velocity changes. The proposed algorithm is based on a sliding mode controller applied to the quadrotor translational dynamics considering the slung-mass angle as feedback. A Lyapunov candidate function is used to demonstrate system stability. https://www.ngetikin.com/limited-save-Apple-iPhone-14-Pro-Clear-Case-with-MagSafe-save-big/
