文中提出了对线性自动调节系统的一个环节或一个组成部分进行D-域分划的方法。利用这种方法可以判定当该环节或该部分具有各种频率特性时系统特征方程的负实部根的相对数目。文中也提出了利用分划曲线来判定系统特征方程具有全部负实部根的方法。在本文的后一部分,以一个具体系统为例,说明所提出的方法有时可以和谐波平衡法结合使用,以解决含有单值非线性元件的系统的稳定问题,文中列有计算结果与实验数据。
In this paper, we present a method to divide D-domain into one part or a part of linear automatic regulation system. Using this method, we can determine the relative number of negative real roots of the system characteristic equation when the link or the part has various frequency characteristics. The paper also proposed the use of the partition curve to determine the system characteristic equation with all negative real roots. In the latter part of this paper, taking a concrete system as an example, it shows that the proposed method can sometimes be used in combination with the harmonic balance method to solve the stability problem of systems with singular value nonlinear elements. The calculation results and experimental data .
