In this paper. the question of compound guidance about mid - long range air - to - air missle to be considered. the main contributions are as follows : first, two midcourse guidance laws are given. that is optimally predictable pn micourse guidance, which is suitable for middle range missle, and singularly perturbed midcourse guidance. which is suitable for long range missle guidance ; then two terminal guidance laws are given. that is variable structure guidance, which is suitable for passive radar guidance. and optimal guidance which is suitable for active radar guidance ; and then the error sourses of hand - off are researched, the hand - off law is given at the time ; fmally, the midcourse guidance laws and terminal guidance laws are tested by simulation, and the whole trajectory simulation are given through hand - off law, and the results are satisfied
主要工作如下：首先研究了用於中遠程空空導彈復合制導的兩種中制導律，即用於中程導彈的最優預測比例導引中制導律和用於遠程導彈的奇異攝動中制導律，它們均有很好的中制導性能，能夠滿足中末制導的交班要求；接著研究了兩種末制導律，即用於被動雷達末制導的變結構制導律和用於主動雷達導引頭的最優末制導律，均適用於復合制導末制導段；然後分析了中末制導的交班誤差源，討論了用於復合制導的交接律；最後通過模擬，驗證了提出的中制導律和末制導律，結合提出的交接規律，在不同的情況下對中末制導段彈道進行了模擬驗證，結果證明文中提到的中末制導律能夠達到性能指標要求。 -
Since sontag - type control based on control lyapunov function is an important control law in robust stabilization of affine systems, we point out that is a kind of variable structural control in essence. due to this recognition and the fact that control lyapunov functions are difficult to be constructed, we propose the concept of weak control lyapunov function and then prove the stabilizing property and the robustness of sontag - type control. using the way of proposing the control lyapunov function and the special structure of sontag - type control, we investigate the dissipassivation control of a kind of perturbed nonlinear systems
基於控制李雅普諾夫函數的sontag - type控制，是仿射系統魯棒鎮定研究中一種非常重要的控制律，通過研究我們發現，該控制律實質上是一種變結構控制；基於這一認識，也考慮到控制李雅普諾夫函數難于構造，我們抽象出弱控制李雅普諾夫函數概念，並證明了基於弱控制李雅普諾夫函數的sontag - type控制的鎮定作用和優化特性；借鑒控制李雅普諾夫函數的抽象方式以及sontag - type控制的特殊結構，探討了一類受擾系統的耗散化控制；探討了齊性度理論與控制李雅普諾夫函數相結合的鎮定設計問題。
