摘要
DEDS的分析总需要将状态空间表达式变为输入/输出表达式,需要进行A~*的运算.这在min max<γ,δ>代数中是一项十分复杂的任务。本文引入一种模型降维的方法,可使求星运算由矩阵情况转为标量情况,为系统分析提供了方便。
For system analysis of DEDS, it is inevitable to transform the state space expression into input/output expression and then calculate A*. However, it is quite a task in minmax<γ,δ>lgebra. A simple and effective method is therefore put forward to reduce the dimension of a model, by which the star operation can be put in case of scalar instead of matrix.
