摘要:

设计了一种应用于准分子激光器的高精度温度控制系统,可对准分子激光器放电腔的温度进行实时采集、显示、控制,达到维持激光器腔体温度恒定的目的,从而改善激光器的工作性能如能量稳定性和使用寿命等。系统采用飞思卡尔单片机,以比例阀作为控温执行器件,并且设计了软硬件和优化的控制算法。实验结果表明:在三种不同PID控制方式下,系统控制精度皆能达到±0.2℃;在改进的智能PID控制下,系统超调变小、调节时间减少;在100Hz和500Hz不同重频条件下,系统采用智能PID控制时,运行稳定。因此,本系统可为激光器的运行提供良好的温度控制环境。

Abstract:

The stability of temperature in the chamber of excimer laser has a great effect on working performance of the excimer especially for the stability of the output energy and the laser’s useful life .So it is very important to keep the chamber temperature constantly. Based on that, a high precision temperature control system of excimer laser was designed, together with its composition and working principle. Meanwhile ,the software and hardware and optimization control algorithm were designed. Experimental results indicate that the designed system has superior control precision which provides a favorable temperature environment for the laser’s operation.

Key words: laser techniques, temperature control, intelligent PID, excimer laser, algorithm
