本文结合导弹比例制导理论和过载控制理论,重点研究了基于过载增稳的无人机纵向姿态控制技术,形成了以俯仰角比例反馈为外环和以过载复合控制为内环的复合增稳控制方案,对比仿真验证表明,相对于基于俯仰角与俯仰角速率的常规PID控制技术,在具备相同的快速性、无超调、零静差指标条件下,基于法向过载增稳的纵向姿态控制技术可以有效地同时兼顾操纵性与稳定性,并且具有更强的抗干扰能力。 Based on the theory of missile guidance and overload control theory, this paper focuses on the longitudinal attitude control technology of UAV based on overload stabilization, and forms the composite stability control with the proportional feedback of pitch angle as the outer ring and the overload compound control as the inner ring The simulation results show that, compared with the conventional PID control based on pitch angle and pitch rate, the longitudinal attitude control based on the law of normal overload stabilization with the same rapidity, no overshoot and zero static index Technology can effectively take into account both maneuverability and stability, and has a stronger anti-interference ability.
