摘要
对一类脉冲调宽采样控制系统提出了HDS(混合动态系统 )的模型 .这种新模型的优点在于 ,不仅对传统意义下的采样时刻的动态变量进行分析 ,而且可以对任何时刻的状态进行分析 .这里构造了混合状态空间中的不变集 ,证明了系统在HDS意义下的渐近稳定性 .
The model of HDS is considered with regard to a class of pulse-width-modulated sampling control system. The new model has the virtues that it can analyze not only the dynamical variables in the conventional senses at the sampling time but also the states at any time. Invariant sets of HDS are constructed in hybrid state space, and then the system's asymptotic stability is proved in the sense of HDS.
