摘　　要：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.Under the condition of the variable sampling interval belonging to the pulse-width modulator contained in the control system, the stability of the pulse-width-modulated systems is discussed. 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.
