中子管内潘宁离子源的建模与控制

由于中子管内离子源电流滞后于储存器电流，导致离子源电流的调节速度和稳定性不够高，进而影响中子产额的稳定性。本文在分析大量实验数据的基础上，建立了中子管离子源的数学模型，设计出相应的PID控制算法。经测试表明：所构建的离子源模型与实际离子源工作情况符合较好，改进的控制算法能减少稳定离子源电流所需时间，提高中子产额的稳定性。

Modeling and Control of Penning Ion Source in Neutron Tube

Because the ion source current in the neutron tube lags the storage current, the regulation speed and stability of the ion source current are not high enough, and then the stability of neutron yield is affected. Based on the analysis of a large number of experimental data, the mathematical model of the neutron tube ion source was established, and the corresponding control algorithm was designed in this paper. The test results show that the constructed ion source model agrees well with the condition of actual ion source. The improved control algorithm can reduce the time for stabilizing the ion source current and increase the stability of neutron yield.
