Abstract

This paper deals with the adaptive retuning of a feed-forward controller, under the normalized lattice form, for a parameter-varying closed-loop system. The objective is to tune the controller in real-time during specific flights so that it does not need the adaptive part in nominal operation. The method was developed to help aeronautical design engineers to retune specific feedforward control laws at the early stage of the design process, i.e. when aircraft models are not fully reliable. The idea is to give more weight to the system itself in the control laws tuning process. Using a design method based on inverse simulation, we use a combination of adaptive filtering, local learning and optimal control techniques to achieve a real-time tuning. The method consists in estimating the system’s inverse response in real-time using feedback control and in locally retuning the control law, whose parameters are interpolated using neural networks. The method is tested on the airbrake compensation of a civilian aircraft.
