Abstract

In this paper, two strategies for the design of controllers based on a simplified LPV model of a UAV (longitudinal flight dynamics) are presented. The simplified LPV model is first derived from a UAV LPV model over the entire range of the cruise speed. The dependence of the LPV model on the varying parameter is reformulated in terms of a mu synthesis problem. A straight mu design and a gain-scheduling mu control scheme have been considered. Simulation results of the closed loop system comprising the controllers and original state-space models are presented and compared
