我们考虑已知两个稳定控制器的控制系统。前者是“最优”的，但是局部的，后者是全局的。我们寻找一个统一的控制律，提供全局稳定的局部最优控制器。我们研究了几种基于连续、不连续、混合、时变控制器的解决方案。选择控制器的标准之一是全局渐近稳定性对测量噪声消失的鲁棒性。这促使我们特别考虑混合系统的 Krasovskii 解决方案的一种推广。
We consider control systems for which we know two stabilizing controllers. The former is "optimal" but local, the latter is global. We look for a uniting control law providing a globally stabilizing locally optimal controller. We study several solutions based on continuous, discontinuous, hybrid, time varying controllers. One criterion of selection of a controller is the robustness of the global asymptotic stability to vanishing measurement noise. This leads us in particular to consider a kind of generalization of Krasovskii solutions for hybrid systems.
