Performance Comparison for Fuzzy based Aircraft Pitch using Various Control Methods

Aircrafts differ from other automobiles because of their greater freedom of motion. Hence for an aircraft stability and control are composite. Yaw, Roll and Pitch are the three elementary control maneuvers of an aircraft. Aircraft employs pitch control to climb or descend. Pitch control is preeminent in ensuring the intrinsic safety of passengers and the aircraft stability. This paper aims to investigate few control techniques for the aircraft pitch system. Pole placement, PID controller conventional and Fuzzy tuned, LQR and GA tuned LQR control schemes are interpreted through simulation. MATLAB is employed to procure the simulation results. Based on time response specifications, qualified assessment of abovementioned methods is presented in the paper. Also, the robustness of the control schemes has been analyzed. An account of comparative results on application of these control to aircraft pitch has been obtained and described. It has been observed that proper tuning will result in improvement of performance.
