摘要
首先分析了导弹制导控制系统被等效为二阶模型时其动态指标对弹道稳定性的影响,在此基础上提出了一种简单快捷的动态性能测试方法,将弹体简化模型实时解算,并将计算出的弹体运动信息实时注入导弹的反馈控制回路,使导弹控制回路闭环。利用时域方法测试出制导控制系统动态特性曲线,与数字仿真计算出的标准曲线对比,即可评估其性能是否满足动态指标的要求。给出了测试实例,证明方法是有效可行的。
Dynamic characteristic of missile guidance and control system influence on trajectory stability are analyzed as it is equivalent to second order model, and a brief dynamic test method is invented based on it. First, the simplified missile model in real time is calculated, and then the missile movement data is infused into missile feedback control channel to lead the loop closed. Finally, time domain measure is used to test the dynamic characteristic curve of this guidance and control system, and compared with standard curve come from digital simulation, so whether the performance is content to dynamic indexes can be evaluated. The example and its result are given and the availability are proved.
