摘　　要：机械制冷机温度控制算法中控制参数的取值可直接影响机械制冷机的控温稳定性能。基于机械制冷机温度控制算法原理,结合制冷机温度控制特性,提出一种简化的控制参数整定方案,然后通过仿真和实验对该理论进行验证,并对机械制冷机的温度控制稳定性能进行分析研究。The value of the control parameters in the mechanical cryocooler temperature control algorithm can directly affect the temperature control stability of the mechanical cryocooler.In this paper,based on the principle of temperature control algorithm of mechanical cryocooler,combined with the temperature control characteristics of cryocooler,a simplified control parameter setting scheme was proposed.Then the theory was verified by simulation and experiment,and the temperature control stability of mechanical cryocooler was analyzed and studied.
