摘要
在认定降压软起动系统只具有1个自由度的基础上,指明描述软起动过程的所有物理变量相互之间存在着映射关系,讨论了不同闭环理论上的同一性,不同闭环物理实现的特殊性,从而得出“一律通过电流闭环实现软起动的合理性”的结论。
The paper affirms that the motor soft-start system with invariable frequency is 1-freedom dimension system. All the physical variables describing the starting process are related by mapping. Therefore, identical starting process can be realized by means of different control loops, such as voltage loop, current loop, etc. After analyzing and comparing the physical specialties of all the possible loops, the paper makes it certain that realizing soft-start uniformly by means of current loop is reasonable.
