Abstract

This paper focused of a robust flight control system (FCS) for a small UAV. The main objective of this design is to ensure the small UAV can fly safely in severe gusty conditions. The Superaugmentation FCS consisted of Stability Augmentation System (SAS) and Command Stability Augmentation System (CSAS) was developed in UTM-LST to improve the dynamic characteristics of the longitudinal stability of UAV; i.e UTM Camar. A combination of the variable stability technique along with advanced flying and handling qualities (FHQ) requirements are used to reduce the gust effect on the aircraft or UAV. The results obtained from the simulation studies showed that the superaugmented aircraft can be operated in severe gust environments than augmented aircraft. The result from here has reduced strain on the elevator activity in both extreme and calm weather conditions. Moreover, the superaugmentation FCS in the longitudinal axis meets the requirements of the level 1 handling qualities specification in flight phase.
