Conventional PID, Adaptive PID, and Sliding Mode Controllers Design for Aircraft Pitch Control

Abstract

In this paper conventional PID, Fuzzy PID and Sliding Mode (SM) controllers have been designed and analyzed for the pitch control of an aircraft. The main purpose is to stabilize the aircraft in case of any external disturbance. An appropriate mathematical model for the longitudinal motion of aircraft is considered. Simulations are performed in MATLAB Simulink for the proposed controllers and results are critically and analytically discussed. Furthermore, analysis based on different performance measures i.e. Integral Squared Error (ISE), Integral Absolute Error (IAE), rise time, settling time, and under shoot are performed to compare the response of the controllers. Besides in comparison, the simulation results validate the robustness and better performance of SMC and Fuzzy PID for pitch control of an aircraft.
