齊夫定律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。
