Power linear ordinary differential equation is a hot research problem in network control field, and is discussed in this paper. Several ordinary differential formula is derived with parameter taken special value. The numeric models are given by using difference methods of Eula, four order R-K and Adam. The Adam difference method has high accuracy when time(More)
