Study on Adaptive Control of Cold Finger Temperature for a Miniature Split Stirling Refrigerator with Double Drive Control

This paper discusses a CARIMA model based on minimum variance and pole placement implicit algorithm with on line choice of weighting terms, and its application to the adaptive control of cold finger temperature for a miniature split Stirling refrigerator with double drive control. The simulation and real time control experiment results show that the closed loop system has strong robustness stability, and can overcome heat load disturbance effectively. As a try, authors have successfully used the golden section adaptive controller as a starting controller, which has advantages of simplicity, reliability and good performance.
