Velocity-free Attitude Control of Quadrotors: A Nonlinear Negative Imaginary Approach
Ahmed G. Ghallab, Ian R. Petersen
In this paper, we propose a new approach to the attitude control of quadrotors, by which angular velocity measurements or a model-based observer reconstructing the angular velocity…
