The concepts of grey systems and grey characteristics given in Refs. [1] and [2] are extended to grey dynamics and the ideas of grey dynamic mapping and the mapping of grey dynamic design are developed so as to ensure a higher adaptability of the control system. A control device designed on this principle can be used to control the spindle system and feed system of boring machines with different powers and parameters and it can also be used to control simultaneously more than two dynamic systems. It has been adopted in production with fairly good dynamic behaviour.

本文发展了文献[1]、[2]提出的灰色系统与灰色特性的概念,将其引伸和推广为灰色动态,进而提出了灰色动态映射和灰色动态设计映射,从而保证控制系统具有较强的适应性.以此观点设计的同一套控制装置,可以控制容量和参数都相差较大的镗床主轴系统和进给系统,也可以控制两个以上的动态系统.本系统已用于生产实际,并有良好的动态品质.

Using the concept of successive pole shifting by the state controller of the white system in Ref. [1], the pole-assignment problems of the grey system are studied. The concepts of dot-pattern shifting (white state feedback) and block-pattern shifting (grey state feedback) under different conditions are proposed and the pole-assignment method for the grey control system is obtained. Two simple examples are given for illustrating the concept and its implications.

本文利用文献[1]的方法,研究了灰色系统中的极点配置问题;提出了不同情况下的点状漂移(白色状态反馈)和块状漂移(灰色状态反馈)的概念,给出了灰色控制系统的极点配置方法。

In this paper the problem of stability of grey linear time-invariant systemsis investigated in virtue of the properiest of non-negative irreducible matrices.Besides,the sufficient criterion for stability of grey linear time-invariant systems aregiven.The criterion obtained here is helpful to the analysis of the stability of lineartime-varying systems as well as grey systems.As an illustrative example of the crite-rion,the sufficient condition is given under which the stability of linear time-varyingsystems is guaranteed.And in terms of the sufficient condition it is much more conve-nient and simpler to judge Whether some linear time-varying systm is stable or not.

本文利用非负不可约矩阵的性质分析了灰色线性定常系统的稳定性问题,给出了灰色线性定常系统稳定性充分判据。所得判据不仅可用来分析灰色线性定常系统的稳定性,而且可用来分析线性时变系统的稳定性。作为所得判据的应用实例,本文还给出了确保线性时变系统稳定的充分条件。借此,可使很大一类线性时变系统的稳定性判定问题变得十分简单。
