Stabilization of a nonlinear system that arises in the context of vision based landing of an airliner

International audienceThe problem of stabilizing a nonlinear system when the variables are not accurately measured and cannot be differentiated arises when it comes to use direction measurements to one point in the environment. We here propose to adapt a recent backstepping technique with delay to the specificity of this problem. The proposed method was first motivated and thus finally applied to the vision based control problem of a landing airliner
