High AOA decoupling control for aircraft based on ADRC
作者: LIU   Junjie   SUN   Mingwei   CHEN   Zengqiang   SUN   Qinglin   来源: Journal of Systems Engineering and Electronics 年份: 2020 文献类型 : 期刊 关键词: disturbance   allocation   linear   attack(AOA)   decoupling   active   control   observer(LESO)   technology   rejection   extended   high   of   thrust   angle   state   control(ADRC)   Vector  
描述: In this paper, a practical decoupling control scheme for fighter aircraft is proposed to achieve high angle of attack(AOA)tracking and super maneuver action by utilizing the thrust vector technology. Firstly, a six degree-of-freedom(DOF) nonlinear model with 12 variables is given. Due to low sufficiency of the aerodynamic actuators at high AOA, a thrust vector model with rotatable engine nozzles is derived. Secondly, the active disturbance rejection control(ADRC) is used to realize a three-channel decoupling control such that a strong coupling between different channels can be treated as total disturbance, which is estimated by the designed extended state observer. The control surface allocation is implemented by the traditional daisy chain method. Finally,the effectiveness of the presented control strategy is demonstrated by some numerical simulation results.
