| Abstract: | In this paper, we studied the characteristics of mechanical cryocooler temperature control system from drive control circuit, cryocooler compressor, cryocooler cold finger and cold platform Dewar components.The physical characteristics of the transfer function were revealed between the input voltage and the output temperature. The system temperature control simulation platform of mechanical cryocooler was established based on Simplorer. The simulation platform could reflect the changes of different physical quantities in the control system in real time.The simulation results were compared with the experimental results to verify the feasibility of the simulation model. Through the simulation platform, the effects of thermal load changes, environment temperature changes and temperature measurement signal noise on the temperature control system of the mechanical cryocooler were analyzed. |
