将RS-485用于数字发动机控制应用

Ⅰ.简介 数字发动机控制采用数字处理器来控制电动机的运转.一般情况下数字处理器可采用一种或多种反馈方式,使其构成一个闭环系统.这可比作模拟控制系统和开环传动系统.

The Assodated Matrices of Ap, n, 4p-5 Polyhedra and their Admissible Onerations

In this paper we describe the decomposition problem of a special kind of Ap,n,4p-5 polyhedra by using the associated matrices and their admissible operations.
