本文讨论了指令制导的地空导弹法向过载的等强限制问题。在假定弹上从指令电压到过载的稳态传递系数为常数的前提下,在制导站中如对λ、u_k进行限幅,且满足u_(k0)=Kλ_0时,将得到正八边形的法向过载限制规律。它以8％的误差近似地实现了法向过载的等强限制,为制导系统的设计提供了依据。 In this paper, we discuss the isoquercivity limitation of the command-guided surface-to-air missiles in the normal overload. Assuming that the steady-state transfer coefficient from the command voltage to the overload on the projectile is constant, if the λ, u_k are clipped at the guidance station and u_ (k0) = Kλ_0 is satisfied, a regular octagon method To limit the law overload. It approximately equal to the error of 8% to achieve the normal strength of the overload limit, the guidance system for the design provided the basis.
