DESIGN AND IMPLEMENATION OF SELF- TUNING FUZZY PID CONTROLLER FOR PITCH AUTOPILOT USING MATLAB/SIMULINK

Abstract

The main objective of this thesis is to design a fuzzy PID controller of a longitudinal autopilot for a Transport Aircraft. We design the self-tuning PID parameters so as to improve the system response and performance, to reduce the error and cost, and to make a PID controller more reliable for industrial processes. It is assumed that the longitudinal aircraft motion is a short period of motion. We examine the PID fuzzy controller using MATLAB/Simulink toolbox. The simulation shows that the self-tuning PID fuzzy controller realize a good dynamic behavior of the pitch-attitude autopilot and give a better performance compare with a conventional PID controller.
