    摘要: Systems and methods for regulating, for example, the temperature of high temperature superconducting (HTSC) thin film filters used in connection with a Stirling cycle cryocooler. The system employs a digital signal processor-based control system. The system includes a cryocooler drive control loop for controlling the cryocooler drive in response to a measured cryocooler driving current and a cryocooler driving current set point. The system also includes a temperature control loop for generating the cryocooler driving current set point in response to either a cooldown profile algorithm or a comparison between a measured temperature and a set point temperature stored in DSP memory.
