关于KZ──D系统调速指标D和S定义的探讨

A Study of the Definitions Definitions of Speed Control Target (D)and Steady Error (S) In KZ-D System

本文通过对现有书籍和文献中有关直流调速系统的调速范围Ｄ和静差率Ｓ各种定义的分析，研究了ＫＺ—Ｄ系统，指出原有定义中的不尽合理之处．并在此基础上，避开非线性区，对调速范围Ｄ和静差率Ｓ的原有定义进行了扩展、引申和部分修正．对如何测试、分析或设计一个实际的ＫＺ—Ｄ调速系统，具有理论指导意义和实用参考价值．

Through analysing various definitions on speed control extent(D)and static error(S) of the D.C.speed control system appearing in existing bobs and documents,this paper makes a study of the KZ-D system and points out the imperfect statements in the original definitions.With the non-linear area excluded,the original definitions are expanded, extended and partly revised. The revised definitions have certain theoretical significance and some practical reference value in testing,analySing and designing a KZ-D system.
