The invention belongs to the technical field of aircraft flight control, and particularly relates to an unmanned aerial vehicle large-gradient stable disc maneuvering control method which comprises the following specific steps: a control scheme and a control law of an elevator channel, an engine channel, an aileron channel and a rudder channel are provided; an elevator channel adopts a lifting speed attack angle and pitch angle rate cascade control structure to prevent stall in the maneuvering process; the engine channel takes the longitudinal acceleration as an inner ring and the indication airspeed as an outer ring to realize quick response of the speed; the aileron channel takes rolling angle rate control as an inner ring, and an outer ring controls a rolling angle to realize large-gradient rolling circling motion; the rudder channel is used for stabilizing and eliminating adverse sideslip generated by large-gradient rolling, sideslip-free turning is achieved, and stability and controllability of course dynamic change are guaranteed. The unmanned aerial vehicle can be prevented from stalling due to the too large attack angle in the maneuvering process of the large-gradient stabilizing disc, and stable circling of the unmanned aerial vehicle under different conditions is achieved.
本申请属于航空器飞行控制技术领域,尤其涉及一种无人机大坡度稳盘机动控制方法,其具体步骤包括:升降舵通道、发动机通道、副翼通道及方向舵通道的控制方案和控制律;升降舵通道采用升降速度‑迎角‑俯仰角速率级联控制结构,防止机动过程失速;发动机通道以纵向加速度为内环,指示空速为外环实现速度的快速响应;副翼通道以滚转角速率控制为内环,外环控制滚转角实现大坡度滚转盘旋运动;方向舵通道用于增稳,消除由大坡度滚转产生的不利侧滑,实现无侧滑转弯,保证航向动态变化的稳定可控。本发明能防止大坡度稳盘机动过程中迎角过大失速,并实现不同情况下无人机的稳定盘旋。
