Pilot-induced-oscillations alleviation through anti-windup based approach

Abstract

The chapter is dedicated to the optimization of a well-known structure of compensators: the anti-windup scheme. This approach belongs to the saturation allowance control class which aims to exploit at the most the actuators capabilities. The objective of this chapter consists of adapting and developing the anti-windup compensator design to some particular classes of nonlinear actuators presenting both magnitude and rate saturations. It is illustrated on the lateral flying case for a civil aircraft in presence of aggressive maneuvering of the pilot. A completemethodology is then proposed comparing several approaches including given anti-PIO filters.
