制导炸弹可以分为三个回路,俯仰回路、侧向回路和滚转回路。本文主要针对制导炸弹的俯仰平面进行研究。首先必须要建立制导炸弹的模型,通过空间物体运动可以看作物体质心的平动以及绕质心转动这一原理来实现。其次要设计一个合适的控制系统,保证制导炸弹的稳定飞行和对指令的跟踪。然后,在根据具体的条件设计导引律来确定制导炸弹的飞行路径。在最后,编写MATLAB全弹道数字仿真程序来对设计内容进行验证。

Title Design and Simulation of longitudinal autopilot for guided bomb
Abstract This paper focuses on the guidance and control system of the guided bomb。With the appearance of the electronic computer, the research of guided bomb in the guidance and control system is a big step forward。For guided bombs, in theory, it is required to have stability and fast, in practical applications, it is also required to be operational and achievable。
The guided bomb can be pided into three loops, pitch loop and lateral loop and roll loop。In this paper, we mainly study the pitch plane of the guided bomb。First, the model of guided bomb must be set up。Through the movement of space objects can be regarded as the center of mass movement and rotation around the center of mass of this principle to realize。Secondly, a suitable control system is designed to ensure the stability of the guided bomb and the tracking of the instructions。Then, in accordance with the specific conditions, the guidance law is designed to determine the flight path of the guided bomb。In the end, the preparation of MATLAB full trajectory digital simulation program to verify the design content。
