Quadrotor multibody modelling by vehiclesim: adaptive technique for oscillations in a PVA control system

Estelles, S. and Tomas-Rodriguez, M. (2015). Quadrotor multibody modelling by vehiclesim: adaptive technique for oscillations in a PVA control system. Journal of Vibration and Control, doi: 10.1177/1077546315619776

Abstract

The work presented here covers the detailed modelling and trajectory control for an elastic bladed quadrotor vehicle. The benefits of using VehicleSim modelling software are also discussed. The authors present a full elastic structural and dynamical model as well as two different aerodynamic models. These two aerodynamic models differ from each other on their level of complexity and therefore, accuracy. The control methodology employed to stabilize and guide the vehicle is PVA (ProportionalVelocity-Acceleration), derived and implemented by using Simulink. As it will be shown, it stabilises and provides satisfactory quadrotor trajectory tracking. Since the control methodology feeds back the acceleration of the vehicle, and this acceleration has an oscillating nature, an adaptive process has been designed and introduced into the vehicle’s model in order to avoid the oscillations’ transmission to the control system, showing how it reduces the amplitude of the control actions
oscillations.
Results of simulations and discussion on them are also provided at the end of this
article.
