本文叙述了一种快速选择飞航式导弹滚动回路自动驾驶仪平飞段参数的方法。这种简便的方法,只需代入公式计算、画出根轨迹,就可以很快地选定参数,对于缺乏经验者尤为适合。这个方法的可行性已在部分型号的滚动回路驾驶仪平飞段参数选择中,初步得到证实。一般飞航式导弹滚动回路驾驶仪均采用角度,角速度信号反馈的调节规律,以提供弹体一个固定的滚动基准。选择这两个信号的传动比,通常是据经验固定其中的一个,从分析线性三阶系统的动特性着手选择另一个,然后再反复验证,比较繁杂。本文叙述的快速选择参数的方法包括角度传动比的选择,角速度传动比的选择以及稳定 This paper describes a method for quickly selecting the parameters of the flight stage of the autopilot for the flight-type missile rolling loop. This simple method, simply substituted into the formula calculation, draw the root locus, you can quickly select the parameters, especially for inexperienced. The feasibility of this method has been initially confirmed in the selection of parameters for some types of rolling-loop pilot flying section. General flight missile rolling loop pilot are used angle, angular velocity feedback regulation of the signal to provide a fixed roll body projectile. The choice of the transmission ratio of these two signals is usually based on empirical one of them. Starting from the analysis of the dynamic characteristics of a linear third-order system, it is more complicated to select one and then to verify repeatedly. The methods described in this paper to quickly select parameters include the choice of angular gear ratio, the choice of angular velocity gear ratio, and the stability
