By the methods it is assumed that a structural system can be reduced to a lumpedparametersystem, of which the mass matrix is diagonal.
方法假定结构可以简化为集中参数系统,其质量矩阵是对角的。

In an engineering control system it is of great importance that the control object is described by a distributed parametersystem while the controller is governed by a lumpedparametersystem.
The system model comprises the dynamic heat exchanger model based on the lumpedparameter method and moving phase boundary method, and the stable flow models of compressor and expansion valve.
