摘要

摘要:
为了降低探测器的噪声与暗电流，使光谱仪的CMOS探测器获得更准确的光谱曲线，设计了探测器温度控制系统。本系统核心采用基于现场可编程逻辑门阵列（FPGA）的增量式比例-积分-微分（PID）控制算法。在传统控制算法的基础上，增加了抗积分饱和控制，并且在PID算法的前端增加了对目标值的过渡过程，实现探测器温度变化速率可控的同时，也解决了超调过大的问题。多次整机环境实验表明，在轨环境温度条件下、40 °C温差范围内，系统可以控制探测器以指定温变速率4.5±0.05 °C/min达到任意温度，并且在该温度下稳定工作，温度变化范围为±0.1 °C。相比于传统模拟PID控制方法，具有灵活度高，稳定性强等优点。制冷到−10 °C时，探测器的噪声得到了有效的抑制。

Abstract:
A temperature control system that employs an incremental PID algorithm based on FPGA technology has been developed to decrease detector noise and dark current while generating an enhanced spectral curve. Considering the current temperature and the control parameters, the appropriate control quantity is calculated to bring the detector to the target temperature. Controlling the temperature change rate of the detector is realized through front stage control, effectively solving the problem of overshooting. Several environmental tests conducted on the entire machine indicate that it control the temperature of the detector to reach any desired temperature within a specified temperature difference range of 40 °C at room temperature. The sensor temperature has a margin of error of ±0.1 °C. Compared to the conventional analog PID control method, this method offers significant advantages of high sensitivity and strong stability. At a temperature of −10 °C, the noise of the detector is substantially reduced.
