轉向與姿態導控系統設計(I)

Abstract

本計畫探討直接攔截命中的飛彈防禦系統。所提出的攔截飛彈由一節推力級和一個配 有紅外線尋標器的殺手彈頭組成。本計畫要研究的主題包括（一）發展一個三自由度 動態攔截模擬的程式（二）利用參數化的攔截模擬訂定主要子系統的規格（三）設 計以開關式推力器為致動器的轉向及姿態控制系統來達到歸向攔截的要求（四）設計 中途導引律及由推力向量為致動器的飛行控制系統。除了提出控制系統設計及方法 外，本計畫的研究成果亦將一些子系統的規格如地面雷達的準度、尋標器的最小鎖定 距離、轉向推力器最小燃料質量、轉向控制系統的頻寬等。

The proposed three-year research will study missile defense system with a hit-to-kill scenario. The proposed interceptor consists of a booster stage and a kill vehicle equipped with an infrared seeker. The tasks includes development of a three degree-of-freedom simulation program for interceptor-target engagement, parametric simulations to determine specifications for various subsystems required for a successful intercept, the design of divert and attitude control systems employing on-off thrusters for homing phase, the design of mid-course guidance and thruster vector based flight control system. In addition to specific control system design method developed, the results from this research is expected to give preliminary system level specifications such as ground based radar accuracy, seeker lock-on range and accuracy, divert propellent mass, and bandwidth of divert control system.
