为了解决传统RF SQUID工作点手动调节,人眼观察输出波形,调节工作繁琐,不适合野外工作的问题,提出一种基于最速下降法的非线性二元函数极值搜索最佳工作点算法。采用最速下降法求函数极值的方法,利用最速下降法在最小值搜寻的迭代原理,使RF SQUID自动搜索到最佳工作点,开发了相应的工作点搜索软件,并将该应用于高温超导磁力仪RF SQUID的工作点调节中。通过实验证明利用此算法可以使RF SQUID自动搜索到最佳工作点,降低了操作的复杂性,提高了工作效率,满足超导磁力仪在野外勘探工作的要求。

In order to solve the problem of traditional RF SQUID such as manually adjusted working point, observing the output waveform by human eye, tedious adjustment work, not suitable for field work, and so on, an algorithm of non-linear binary function's extremum for search for the best working point was presented based on the steepest descent method. By using the method of steepest descent method to find the function extreme value, and using the steepest descent method in the minimum search iterative principle, the RF SQUID could automatically search the best working point. Developing the corresponding working point search software, and it will be applied to the high-temperature superconductivity magnetometer RF SQUID work point adjustment. Experiments showed that using this algorithm can make the RF SQUID automatically search the best working point, reduces the complexity of the operation, improve work efficiency, to meet the requirements of superconducting magnetometer in the field work.
