Research on the Application of Temperature Control of Large-sided Array Black Body in High Vacuum Cold and Black Environments
In order to meet the infrared load radiation calibration of a certain product in the high vacuum cold black environment,a composite PID control algorithm is designed and adopted.In the vacuum test of the large area array black body multi zone scaler,the high-precision index requirements of the large area array black body multi zone cross coupling temperature control are well met.The segmented approximation temperature control verification based on the combination of fuzzy control and traditional PID with strong engineering practicality has achieved an overall system temperature control accuracy of±0.1 K,meeting the design temperature control requirements.
