What is it about?

The VTOL UAV is equipped with a lift fan and two thrust vector engines. Based on nonlinear dynamic inversion, an two-stage cascaded control allocation method is proposed to solve the redundant and coupled control problems of actuators.

Why is it important?

We put forward a control system which allocates the direct force and moments optimally and synthetically, and makes the UAV show favorable maneuverability in transition flight. This paper is useful to the control system design of VTOL UAV with thrust vector engines and redundant actuators.

Perspectives

The research of this paper is based on a prototype which is designed by my team "Microraptor Works". During this project, we have shared great pleasures of flight vehicle design. In the future, the control system presented in this paper shall be incorporated with the controller of prototype. I hope this research can solve the control problems we met and make our prototype fly in sky with ideal function.
