双重磁检测器直流大电流比较仪的稳定性研究

The Stability of High DC Current Compartator with Double Magnetic Detector

针对传统磁调制式直流大电流比较仪建立数学模型 ,通过理论研究和计算机仿真 ,分析了闭环系统的稳定性问题 .从而提出了双重磁检测器直流大电流比较仪的改进方案 ,同时进行了样机改制 .以实际的样机为对象 ,给出了样机改制前后的稳定性研究结果 .

A traditional mathematic model for the high DC current comparator based on magnetic modulator is constructed. And the stability of the whole system′ close loop is analyzed by the theory research and computer emulation. An improved project for the high current comparator with double magnetic detector is put forward and made. Based on the actual object, the stability before and after the improved project is obtained.
