چکیده

A model for the dynamics of a four rotor vertical take-off and landing (VTOL) vehicle known as an X4-flyer is proposed. The model incorporates the airframe and motor dynamics as well as aerodynamic and gyroscopic effects due to the rotors for quasi-stationary flight conditions. A novel control strategy is proposed for configuration stabilization of quasi-stationary flight conditions. The approach taken involves separating the rigid body (airframe) dynamics from the motor dynamics, developing separate control Lyapunov functions for the coupled systems and then bounding the perturbation error due to the interaction to obtain strong practical stability of the complete system.

Tracking-control investigation of two x4-flyers

Abstract: Two models of mini-flying robots with four rotors called X4-flyer presented and studied for the stabilization. Both cases with and without motion planning are proposed in this paper. The first is called inertial model with axes orientation and the second is called the inertial model without axes orientation. The control algorithm of the X4-flyer is based on the Lyapunov method and obt...

Visual servo control using homography estimation for the stabilization of an X4-flyer - Decision and Control, 2002, Proceedings of the 41st IEEE Conference on

In this paper we study image based visual servo (IBVS) control of a four rotor vertical takeoff and landing (VTOL) craft known as an X4-fEyer. The approach taken is tailored to planar visual targets and is based on a reformulation and extension of 2 2 0 image-based visual servo design [14, 11 to the control of dynamic under-actuated systems. Exponential stability of the closed loop system is pr...

Design of a Controller Allowed the Intuitive Control of an X4-flyer

In this paper, we present a control design for the tele-operation of a miniature unmanned aerial vehicle known as an X4-flyer. A simple dynamic nonlinear model for the vehicle, valid for quasi-stationary flight conditions, is derived as a basis for the control design. To ensure the vehicle remains in the quasistationary flight regime the controller incorporates barrier function on the closedloo...

Towards Dynamically-Favourable Quad-Rotor Aerial Robots

This paper outlines progress towards realising practical quad-rotor robot helicopters and, in particular, the Australian National University’s ‘X-4 Flyer’ platform. Two challenges facing the X-4 are generating sufficient thrust and managing unstable dynamic behaviour. We address these issues with a rotor design technique for maximising thrust and the application of a novel rotor mast configurat...
