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...

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。

BOD-DO dynamics for rivers in Northern China during freeze season were investigated. One type of mathematical model which can be used to describe the dynamics was proposed and parameters:deoxygenation rate K1, reaeration rate K2, BOD-DO sedimentation and resuspension rate K3, were determined by a parameter estimation method using the field data based on the Tumen River. Validation of the model shows that the model can describe BOD-DO dynamics better during that season and therefore can be used with...

本文定量地研究了北方河流封冻期BOD-DO的动态变化规律。提出了一种描述这一动态变化规律的数学模型形式,并且根据在图们江上收集到的实测数据,利用参数估计方法确定了模型中的耗氧系数K_1、复氧系数K_2和BOD沉淀-再悬浮系数K_3.通过实测数据对该模型进行检验的结果证明,它能较好地反映封冻期河流中的BOD-DO动态,可以做为这一时期水质预测与控制的基础。 用数学模型来描述封冻期河流中BOD-DO的变化规律尚属初次,所提出的模型结构形式仍有待于进一步完善。
