This article presents a new control strategy for the well‐known problem of the planar vertical take‐off and landing. The total thrust is computed using a nonlinear feedback compensation so that the altitude reaches the desired altitude. The horizontal position x is then controlled by choosing the orientation angle θ as a smooth saturation function of x andx ˙ . A proof of convergence is presented using a Lyapunov approach. The proposed control strategy is successfully tested in numerical simulations.
