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

介绍一种基于ＣＡＲＩＭＡ模型在线整定加权系数的最小方差、极点配置隐式算法，并将其应用于双驱动分置式微型斯特林制冷机温度自适应控制系统．经数字仿真及实时控制实验，结果表明该系统闭环控制鲁棒稳定性强，能有效地克服未知确定性热负荷扰动，再加上采用黄金分割鲁棒控制器作为自适应控制的启动控制器，整个系统简便实用、工作可靠。

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.
