| 摘 要： | 为在不同条件下由运载姿控系统校正网络实现系统的稳定,根据负阻尼零点网络幅值相同、相位滞后的特性,将其用于校正网络设计以替代常用的正阻尼零点网络。证明了箭机对负阻尼零点网络的可实现性,以及测试的重复性和稳定性。某运载一级姿控系统负阻尼零点校正网络的应用表明,可在速率陀螺安装处一阶振型斜率为正时实现系统的稳定。该方法对其他型号的设计有一定的参考价值。

| Abstract: | To reach the system stability by the revisable network of attitude control system for a launch vehicle under various conditions,the negative damp zero network with the characteristics of the same amplitude and phase lag was applied on the revisable network design to replace the conventional positive damp zero network in this paper.The realization of the negative damp zero network in the onboard computer,and the repeatability and stability were verified in the test.The application of the negative damp zero network on the attitude control system of the first class for some launch vehicle showed that the system stability would be realized when the slope of first order mode shape near the mounting position of the rate gyro was positive.This method was valuable in the design of attitude control system for other launch vehicle. |
