In this paper, some problems for Large Scale Systems theory are discussed. There are: what the Large Scale System (LSS) is; the relationship between LSS' theory and control theory; the relationship between LSS' theory and System Engineering; the relationship between LSS' theory and Cybernetics; the special problems of LSS' theory. In author's opinion, LSS' theory is the important part of the third age of control theory, i.e. the fundamental of the...

In this paper, some problems for Large Scale Systems theory are discussed. There are: what the Large Scale System (LSS) is; the relationship between LSS' theory and control theory; the relationship between LSS' theory and System Engineering; the relationship between LSS' theory and Cybernetics; the special problems of LSS' theory. In author's opinion, LSS' theory is the important part of the third age of control theory, i.e. the fundamental of the total complex automation. On the other hand, LSS' theory is the new stage of development Systems Engineering——Dynamical Systems Engineering. It may also be said, LSS' theory is the new branch of cybernetics ——LSS' Cybernetics. LSS' theory is not the classification of the size of various systems, but it's the methodology of the analysis and synthesis of large complex control and information system. It is the system science of large scale systems.

本文讨论关于大系统理论的几个问题,即:什么是大系统?大系统理论与控制理论的关系;大系统理论与系统工程的关系;大系统理论与控制论的关系;大系统理论的特殊问题。作者认为,大系统理论是第三代控制理论的重要内容,是综合自动化的理论基础。另一方面,大系统理论也是系统工程发展的新阶段——动态系统工程。也可以说,大系统理论是控制论的新分支——大系统控制论。大系统理论不是关于系统大小的分类学,而是大规模复杂控制与信息系统分析和综合的方法学,是研究大系统的系统科学。

The large scale system is a kind of multi-variable system characterized by having a very large number of variables.The application of conventional parameter estimation methods for multi-input and multi-output systems to large scale system are almost impossible,because the computation requirement due to high dimensionality is so tremendous that it should be hard to carry out.This is the difficulty to be surmounted or bypassed when one tries to identify a large scale system.A review of various methods tractable to those problems are introduced hereby.Conceptually,these methods fall into two catalogues,i.e.simplification and decentralization.The simplification procedures for parameter estimation of large scale system are based on perturbation techniques.The decentralization approaches are realized by hierarchical structure methods.They will give either the on-line estimates with the aid of distributed computing system or the off-line estimates with a minicomputer when such a system is unavailable.The discussion involves perturbation theory,hierarchical system theory extended Kalman filter,maximum a posteriori estimation,some iterative methods and recursive methods etc.The emphasis are,however,placed on the conceptual developments.In the conclusion,the advantages and disadvantages of different approaches together with a perspective of future development are discussed.

大系统是一种变量甚多的多变量系统。把通常的多输人多输出系统参数估计的方法用于大系统,则往往因维数太高,使计算量过大,而难于实现。大系统参数估计必须克服这种困难。主要有两个途径:一是简化,二是分散。本文综述了采用这两个途径的现有方法。主要是摄动方法、借助于分布式计算机系统可用于在线估计的递阶结构方法以及用较小计算机就可离线进行大系统参数估计的递阶结构方法。综述着重于阐明主要概念,指出现有方法的优缺点和发展方向。

For the analysis and design of hydraulic systems, especially, for their digital simulation, performance prediction and optimization, the state-space representation of systems needs to be established. This paper introduces a new method for modelling hydraulic systems. This is a general method of establishing the state-space representation of hydraulic systems by the Large Scale Systems theory. This method has special advantages over transfer function analysis and Bond Graph analysis. The larger and more complex the systems are, the more explicit its advantages become. The contents are divided into four sections—the decomposition of systems, the topology analysis of systems, the state-space representation of subsystems and the state-space representation of systems.

液压系统的分析和设计,特别是数字仿真、性能预测和优化,需要建立系统的状态空间表示。本文提供一种新的液压系统模型建立法——系统分析法。它是运用大系统理论建立液压系统状态空间表示的一般方法。系统分析法较之传递函数法和“Bond Graph”法(键合图法)具有特殊的优点,液压系统愈是大型复杂,方法的优点表现得愈为显著。文章分“系统分级”、“系统拓扑分析”、“子系统的状态空间表示”和“系统的状态空间表示”四节,探讨了系统分析法的实施细则,并以常见的采用调速阀的节流调速系统为例说明了方法的具体运用。
