Abstract :
This article deals with the design of a pitch/yaw dynamics load factor autopilot for a 155mm spin-stabilized projectile which is controlled using a nose-mounted course correction fuse equipped with two rotating aerodynamic surfaces. A q-LPV model necessary for controller synthesis, which considers the actual sensor position in the fuse, is proposed. An H∞ loop-shaping design approach is used for the synthesis of two robust reduced order and fixed structure autopilot controller configurations, for one single system operating point. These two structures correspond to two distinct robustness optimization setups and their nominal performance and robust stability properties are evaluated and also compared to full order autopilot configurations.
