摘要: 离散事件决策子系统和数值反馈子系统合成的混合控制系统呈现出复杂的稳定动态 特性.研究了在达到模态切换周期的控制规则下,相应的系统连续状态轨迹的平稳性.给出了具 有较少约束的李雅谱诺夫型判据,不要求全局一致的李雅谱诺夫函数,不要求每个模态下的能 量函数单调递减.Abstract: Stability is a complex issue for hybrid control systems composed of discrete event decision-maker sub-systems and continuous variable dynamic sub-systems. A few Lyapunov-type theorems are extended to guarantee the stability of continuous states of the hybrid control system when its discrete periodic control mode is reached. The new stability conclusions are deduced out, in which a consistent Lyapunov-function for all discrete work modes is not needed, and moreover the energy function is not necessarily to be monotonically decreasing at some control modes.
