Abstract

The evolution of geometric measures (volume, surface area) of sets of attainability of linear controlled mechanical systems with constant parameters is studied. Lyapunov's direct method, the comparison method, and theory of mixed volumes are used. Based on the general comparison theorem, estimates are obtained for the solutions of differential equations with a generalized Hukuhara derivative that describe the evolution of regions of attainability. For linear controlled systems with one degree of freedom, the maximum boundedness conditions are obtained for the area of the set of attainability. Examples of the application of the obtained results are given.

机械系统轨迹集的定性分析

研究了常参数线性控制机械系统可达性集几何测度(体积、表面积)的演化规律。使用了李亚普诺夫直接法、比较法和混合体积理论。基于一般比较定理，给出了描述可达区演化的广义Hukuhara导数微分方程解的估计。对于一自由度线性控制系统，得到了可达集面积的最大有界条件。给出了所得结果的应用实例。
