求解舰船消磁系统S矩阵的一种新方法

A new method to get S-matrix of a degaussing system

利用舰船感应干扰系数矩阵和消磁系统传感器检查绕组电磁常数定义了舰船消磁系统模拟特征矩阵———S矩阵.进一步阐述了用S矩阵模拟产生舰船消磁系统在任意地点和任意姿态下的真实消磁电流的原理方法.在定义消磁系统电流状态矩阵基础上,推导了S矩阵各元素新的数学表达式,从而得到S矩阵一种新的求解和测量方法.

With the coefficient matrix of the induced magnetism of the ship and the electro-magnetic constant matrix of the selected coils in the sensor of the degaussing system, the S-matrix of the degaussing system is redefined mathematically. This new defined S-matrix has its physics meaning more clearly and can be used to create any output degaussing current more conveniently in simulated manner. By a new defined matrix called the state matrix of the degaussing system, the elements of the S- matrix are presented in relatively simple expressions and can be got with a new practical measuring method.
