On-Ground Aircraft Control Design Using an LPV Anti-windup Approach

Abstract

Based on the LFT model of the on-ground aircraft developed in Chapter 6, an anti-windup control technique is proposed to improve lateral control laws which have been designed using classical methods. The original idea of this work consists in taking advantage of a simplified representation of the nonlinear lateral ground forces, which are approximated by saturation-type nonlinearities. The anti-windup compensator is then implemented on the full nonlinear aircraft model using an on-line estimator of the ground forces. Simulations demonstrate the efficiency of the resulting adaptive controller.
