The paper first analyses some defects of existing design procedures, and then puts forward an idea of Root-LocusMethod Correction which removes the need to draw root-locus diagrams.
本文分析了现有离散控制系统设计方法的某些不足之处；提出了一种不必画根迹的根迹法校正的设想；

Analysis and calculation of a practical example show that the results is correct, and is simpler and more accurate with the method developed in this paper than that with root-locusmethod.
实例分析和计算表明，利用该方法所得的结果比根轧迹方法简单、准确。

Furthermore, it performed the parametric analysis in terms of feedback gains and delayed time using the rootlocusmethod, thus obtaining the system's flutter stability boundary.
