| 摘 要： | EMBCCD(Electron Multiplying Back Illuminated CCD)在较稳定的低温环境中工作时可以有效地提高其图像信噪比。针对这个问题设计了相应的PID控制算法,包括PID参数的计算和处理策略、PID算法的实现过程和对EMBC-CD进行精确制冷控制的调试方法。实验结果表明,PID算法可以将温度控制在-10.5℃,精度为±0.5℃,达到了控制目的。

| Abstract: | When the EMBCCD(Electron Multiplying Back Illuminated CCD) is in the stable environment at low temperature,the signal to noise ratio can be improved.For this problem,the PID control algorithm is described,including the calculation of PID parameters and processing strategies,the implementation of the PID algorithm,as well as the debugging method about the refrigeration control of EMBCCD precisely.The experimental results show that the algorithm can make the temperature at-10.5℃with error ±0.5℃. |
