| 摘 要： | 本文根据向量函数J(ω)分析了直流脉宽调速系统的强制振荡和分谐波振荡,确定了系统发生强制振荡和分谐波振荡的条件,指出了系统可能发生分谐波振荡的频率范围,并阐述了系统分谐皮振荡频率与系统自激振荡频率之间的关系。文中所得结论为抑制系统发生分谐波振荡的设计提供了依据。

| Abstract: | Forced oscillation and subharmonic oscillation of DC PWM speed control system are analyzed with vector function J(w). The condition for system forced oscillation and subharmonic oscillation to occur is investigated, that is, the condition that the amplitude of forced signal should be larger than a critical amplitude as follows:Im JThe relation between the self -oscillation frequency and the subharmonic oscillation frequency when the subharmonic oscillation may occur will beThe results can be used as a basis for circuit design to prevent subharmonic oscillation. |
