The invention provides a flight envelope protection method for an unmanned aerial vehicle. The flight envelope protection method comprises the following steps: determining a flight kinetic equation of limitation parameters of the unmanned aerial vehicle under a dynamic balance condition; determining a critical control redundancy vector of the limiting parameter in a dynamic balance state according to the flight equation; a control law of the control system is determined according to the critical control redundancy, and the basic principle of the control law is that negative feedback which is inversely proportional to the 2 norm of the control redundancy vector of the boundary is provided for the system, so that when the aircraft approaches the flight envelope, the control input is gradually reduced. According to the method, the limiting parameters of the aircraft in the whole flight envelope do not exceed the limiting boundary, and the flight safety and reliability are effectively improved.

    本发明提供一种无人飞行器飞行包线保护方法,包括以下步骤:确定无人飞行器的限制参数在动平衡条件下的飞行动力学方程;根据飞行方程确定限制参数在动平衡状态下的临界控制余度向量;根据临界控制余度确定控制系统的控制律,所述控制律的基本原理为:为系统提供与边界的控制余度向量的2范数成反比的负反馈,从而使得当飞行器接近飞行包线时,操纵输入逐渐减小。本发明可使飞行器在整个飞行包线内限制参数均不超过限制边界,有效提升飞行的安全性和可靠性。
