Aircraft gust alleviation preview control with a discrete-time LPV model

This paper deals with a Gust Alleviation (GA) system using Gain-Scheduled (GS) discrete-time preview control. An LPV (Linear Parameter-Varying) model of an aircraft is proposed through a series of approximations of the elements of the state-space matrices based on understanding of flight dynamics. By composing a smaller convex hull and applying GS control, it is shown that the proposed control system effectively attenuates aircraft acceleration in turbulence and it is robust against cruising speed changes through some numerical simulations.
