【摘要】 通过对飞行力学中耦合因素及其对飞行控制影响情况的分析,指出了传统直接力控制技术的不足,提出了基于气动力反馈的直接力控制技术.通过引入气动力控制环节,将飞行控制系统分为动力学控制系统和气动力控制系统两大部分,降低了飞行器空气动力学模型不确定性对运动控制的影响,提高了飞行器运动/姿态控制的解耦精度.仿真结果表明,该方案可以实现飞行器的动力学解耦控制,并对气动面损伤等影响有一定的抑制作用.更多还原

【Abstract】 The coupling factors in flight dynamics and its’ influence on flight control are analyzed,and the shortage of traditional direct force control(DFC) is given.The aerodynamic force feedback based DFC is put forward to improve the performance of DFC.As the aerodynamic force controller is added,the flight control system is divided into the dynamics control system and the aerodynamic force control system.The influence of uncertainty for the aerodynamic model of aircraft on kinetic control is reduced,and the precision of kinetic/altitude decoupling control is improved.The simulation results show that the aerodynamic force feedback based DFC can achieve a good kinetic decoupling control,and have some robustness to small damage of wing.更多还原
