针对非线性飞机的控制问题,提出了一种适用于大攻角气动参数飞机的电传增稳系统设计方法。该方法针对非线性飞机的数学模型,结合广义扩展线性化理论和Matlab符号语言,进行非线性反馈控制系统设计。设计的飞机闭环系统具有稳定性和线性特性,并利用Matlab/Simulink软件仿真验证了其有效性。
Aiming at the control problem of non-linear aircraft, a design method of augmentation stabilization system for the aircraft with aerodynamic parameters at high angle of attack is proposed. Aiming at the mathematical model of nonlinear aircraft, this method combines with generalized extended linearization theory and Matlab symbolic language to design a nonlinear feedback control system. The designed closed-loop system of aircraft has the characteristics of stability and linearity, and its effectiveness has been verified by Matlab / Simulink software simulation.
