Aircraft attitude control system design considering actuator based on improved genetic algorithm

This paper concerns the cross-linking between aircraft attitude control system and actuator, proposes a new method of designing aircraft attitude controller while considering the characteristics and constraints of actuator. The mathematical model of actuator is deduced and a servo controller is designed. Considering the characteristic and constraints of actuator, model of attitude control system is presented based on general dynamic analysis of aircraft. Under the multi-constraints of both dynamic quality and frequency domain margin, multi-objective evolutionary optimization (improved genetic algorithm) is implemented to adjust parameters of the proposed attitude controller.
