分导式多弹头变轨控制稳定性分析与仿真

Analysis & Simulation of Control Stability of Multiple Independently Targeted Reentry Vehicles

弹道导弹弹头分导控制技术的研究是我国导弹技术发展的必然。文章依据所设计的弹道导弹多头分导方案,基于非线性系统控制理论,对分导式弹头在其改变轨道进行机动飞行时的控制稳定性进行了分析,并根据分析结果进行了实例仿真,提出了分导式弹头在机动飞行中的控制稳定的条件性,并验证了分导式弹头机动飞行稳定的控制可行性,为进一步研究弹头分导控制技术奠定了一定的基础。

The control technology of MITRV (Multiple Independently Targeted Reentry Vehicles) of the ballistic missile is an important part of the technology of missiles. This paper analyzes the control system' s stability of MITRV during its proceeding of changing orbit, depending on nonlinear control theory. And according to the outcome of analysis and simulation, it presents the conditional stability of control system of MITRV. At the same time, it proves the feasibility of control system' s stability.
