quasi-stability

A definition on steady-state stability for PWM systems is given and it is proved that many applied proportional PWM systems in the industrial controlled process are with steady-state stability.

在控制系统的脉宽调制器采样间隔可变的条件下,讨论了脉冲调宽系统的稳定性,给出了该类系统具有稳态稳定性的定义,并且证明了在工业控制过程中大量应用的比例型脉冲调宽系统具有稳态稳定性。

The steady-state stability of the system is defined and proved under the condition of variable sampling timelike interval, which is also applied to pluse-width-modulated control system of aptotic sampling period.

对于线性脉冲调宽控制系统给出了更一般的HDS(混合动态系统)的模型,在采样时间间隔为时变的情况下给出了系统的稳态稳定性的定义和证明。
