چکیده

In this paper, hierarchical control of an UAV (unmanned aerial vehicle) is proposed. The proposed controller is made up of two sub-systems, namely inner-loop controller and outer-loop controller. The inner-loop controller is an attitude control system while the outer-loop control system is a trajectory control system. In the proposed architecture, a DFNN-(dynamic-fuzzy-neural-network-) based reference model controller is deployed. Hover motion has been implemented to demonstrate the effectiveness of the proposed controller. Both the PD controller and BP (back propagation) NN-based controller have been developed for the control of an UAV. The input of the DFNN is the position of an UAV while the output is the desired force to control the UAV. Simulation results show that the DFNN has faster convergence speed than the PD and the BPNN. Furthermore, the DFNN is able to produce the desired force to achieve hover motion at any positions in a given area.

Fuzzy Adaptive Control of Unmanned Aerial Vehicle for Carrying Time-Varying Cargo on Predefined Path

At present, the use of unmanned aerial vehicles (UAVs) has been increased dramatically. The reasons for this development are cheapness, smallness, simplicity, and diversity of missions. The simplicity of guidance and control of multi-rotor drones is that they are equipped with an autopilot system. This system is responsible for flying control. UAVs do not have a high weight and often have three...

A nonlinear dynamic inversion-based neurocontroller for unmanned combat aerial vehicles during aerial refuelling

The paper presents the development of modelling and control strategies for a six-degree-of-freedom, unmanned combat aerial vehicle with the inclusion of the centre of gravity position travel during the straight-leg part of an in-flight refuelling manoeuvre. The centre of gravity position travel is found to have a parabolic variation with an increasing mass of aircraft. A nonlinear dynamic inver...
