| Abstract: | The control of split-stirling cryocooler is getting more important since it is widely used in space exploration.A temperature closed loop control system based on FPGA(Field Programmable Gate Array) was developed for given split-stirling cryocooler.The hardware of the system and the sinewave to drive the linear motors were briefly introduced.This paper was focused on the process control of the cryocooler,especially on implementing digital temperature PID algorithm.The function of the controller was tested by tracking the temperature curve. |
