Trajectory Tracking of a 2-DOF Helicopter System using Fuzzy Controller Approach

Abstract

In this paper, the desired pitch and yaw axis trajectories of a 2-DOF helicopter system are tracked. For this purpose, fuzzy system is implemented and its performance is compared with a conventional control approach, namely an LQR controller. In proposed fuzzy system, in order to obtain an optimal fuzzy model for benchmark Unmanned Air Vehicle (2-DOF Helicopter), the parameters of the membership functions at the antecedent part of the fuzzy rules are tuned.
