讨论用于静不稳定弹体的自动驾驶仪的设计原理和控制特性.适当选择阻尼回路的参数能使静不稳定弹体可稳定并可控制.使用静不稳定弹体能显著提高导弹的过载能力,过载能力随弹体不稳定度的增加而增加,但放宽静不稳定度有一定的限度.静不稳定弹体自动驾驶仪要求其阻尼回路的传递系数足够大,时间常数比较小,并且还要求舵机有足够大的输出功率和响应速度. Discuss the design principles and control characteristics of autopilots for static instability projectiles.A proper choice of the parameters of the damping circuit can stabilize and control the static instability projectile.The use of static instability projectiles can significantly improve the missile’s overload capacity, The overload capacity increases with the increase of the instability of the projectile, but there is a certain limit to relax the static instability.The static instability projectile autopilot requires that the damping coefficient of the damping circuit is large enough and the time constant is relatively small, Servo has a large enough output power and response speed.
