文章在分析航天产品真空热试验时被控对象的特点及目前在温度控制方面存在的主要问题及难点的基础上，进行了极点配置自适应PID控制器的设计，并通过2次热真空试验验证了该控制方法的控制效果。结果表明，该PID控制方法具有超调量小、适应性强且在过程中无需手动调节等优点，较好地解决了目前热真空试验中控制系统智能性差和超调量大的突出矛盾，极大地减轻了试验人员的值班强度。

On the basis of analysis on the characteristics of the control objects in the thermal vacuum tests and the current problems and difficulties in the temperature control, an adaptive PID controller is designed. In order to verify this control method, two thermal vacuum tests are carried out. The test results show that this adaptive PID control method enjoys many advantages, including small amount of overshoot and superior adaptability without the need of manual operation in the test. It provides a better solution to the problem in the current control system with the lack of automation and a large overshoot, and thus greatly reduces the labor intensity of manual adjusting.
