敏捷性飞机飞行控制系统设计方法研究

对敏捷性飞机飞行控制系统的设计方法进行了研究，研究表明当飞机进行大迎角机动时，飞机可以获得敏捷性机动能力，在这种情况下，飞机的动力学特性呈现非线性的特征，此时飞行控制系统的设计是一类非线性控制系统的设计问题，设计可采用非线性动态逆的方法进行，为简化控制律和工程因素，重点研究了利用一阶动态作为系统的反馈线性控制，以得到线性化的系统，在此基础设计跟踪控制器，以满足大迎角非线性机动时的性能要求，最后以Ｆ

Study on Designing Approach of Flight Control System for Agility Aircraft

The designing approach of flight control system is studied for agility aircraft.The research indicated that aircraft can attain agility if maneuver as large angle of attack.In above case,the aircraft's dynamics present nonlinear character,so it is a kind of nonlinear control system for flight control system and nonlinear dynamic inversion will be applied to design of flight control system for agility aircraft.In order to predigest control law and use convenient in aircraft,it is emphases to research first order dynamic inversion as control law of feedback linearization for flight control system,then design track controller based on above linear system according to meet handling qualities while aircraft maneuver in large angle of attack.Finally,as a design example,first order dynamic inversion is applied to design of flight control system for F 8 aircraft and the result of simulation that flight control system is operated under a maneuver command of large angle of attack indicates validity of system design.
