摘要

隨著科技日益發達，飛行控制器的研究也持續的受到人類的注意。在眾多不同功能的飛行器裡，飛彈的研究是其中最受到矚目的一種。本篇論文中，我們討論飛彈系統的兩個主要決策部分：導引法則與自動駕駛儀。我們使用線性可微分賽局理論(Linear Differential Game Theory)來實現導引法則，並藉由此法則，使我們的飛彈可以完成攔截機動目標的任務。在自動駕駛儀部分，我們利用順滑模態控制(Sliding Mode Control)來進行設計。在整合飛彈系統中，其穩定性則藉由李奧普洛夫定理(Lyapunov Stability Theory)來分析及證明。在飛彈模型方面，我們使用了無翼面的彈體設計。使用無翼面彈體的好處是可以讓空氣動力學的非線性效應對飛彈的影響減到最小。在動力方面則使用推力向量控制(Thrust Vector Control)及側噴流控制系統(Divert Control System)，這可以讓飛彈的活動範圍自大氣層內延伸至外太空。為了驗證所設計控制器的性能，我們做了多樣的模擬，並且將空氣動力模型包含在其中。最後，利用所得到的模擬結果，來證實整合導引法則與自動駕駛儀的可行性並且比較出不同形式的攔截飛彈所適合使用的交戰場景。

The decision part in missiles: guidance law and autopilot system is presented in this thesis. The guidance law is designed with linear differential game theory in order to consider the motion of target and to minimize the distance between the missile and the target as soon as possible. The autopilot system based on quaternion representation is designed using sliding mode control method to generate the attitude command. The stability of the integrated guidance/autopilot system is proved with Lyapunov stability theory. In addition, two wingless missiles are applied in the thesis in order to reduce the nonlinear effect from the aerodynamics. Furthermore, in order to extend the operation range of missiles from endo-atmosphere to exo-atmosphere, the missiles are equipped with Thrust Vector Control (TVC) mechanisms and Divert Control System (DCS). Finally, various simulations incorporating aerodynamic model are demonstrated to verify the validity of the proposed integrated guidance/autopilot systems, and we compare the performance of the simulations with that from the previous works. Moreover, the simulation results reveal that the mission of intercepting a maneuvering target is successful.
