Longitudinal Motion Control based on Fuzzy logic for small Unmanned Aerial Vehicle

Abstract

This research attempts a fuzzy control design for longitudinal motion of small UAV. Fuzzy logic control is known as an artificial intelligent, nonlinear and rule-based method; therefore no complex model is required for control design. Two loop controls are proposed as an inner loop for pitch control and outer loop for altitude control and a nonlinear small UAV model used comes from simulator based system. The proposed fuzzy flight control is implemented and tested in simulating platform consisting of Mat lab and X-Plane© flight simulator. Numerous simulations were conducted to verify the feasibility of proposed controller. It was shown that inner-loop and outer-loop fuzzy control has good capability for longitudinal motion.
