Adaptive Dynamic Surface Control of Flight with Vector-Coupled Dynamics

Abstract

This study aims to address the issues of controlling angle of attack, sideslip angle, and airspeed of a flight in vectorial form. A novel vector-control structure is developed to transform the attitude and speed control problem into a space-vector tracking problem. Firstly, we establish the flight dynamics with vectorial descriptions, i.e. velocity and angular-velocity vectors in a body-fixed frame. Then multivariable flight controller is proposed based on adaptive dynamic surface control. The theoretical analysis ensures that the states of the system can be enforced to reach a small neighborhood of the desired manifold. Finally, the results of the numerical simulation illustrate the effectiveness and superiority of the combined vector-control scheme.
