Design of Modern and Predictive Controllers for Aircraft Control System

摘要

This paper exhibits a comparative assessment based on time response specification performance between fuzzy and Model predictive control (MPC) for a pitch control system of an aircraft system. The dynamic modeling of pitch control system is considered on the design an autopilot that controls the pitch angle. It starts with a derivation of suitable mathematical model to describe the dynamics of an aircraft. For get close to actual conditions, the white noise disturbance applied to the system. The performances of pitch control systems are investigated and analyzed based on common criteria of step's response in order to identify which control strategy delivers better performance with respect to the desired pitch angle. The design of MPC gave response less quality than that was given from Fuzzy controller but acceptable responses. Finally, It is found from simulation, predictive controller proposed gives the best performance compared to fuzzy and PID controller.
