Paper Abstract

This paper describes the analysis, development, and laboratory testing of a closed loop control system that maintains temperature over a range of 50 to 80 K to +/- 0.01 K. The control loop uses position, velocity, and integrated error information to achieve excellent short-term and long-term temperature stability by modulating the length of the compressor stroke. The resulting control system is compatible with adaptive vibration cancellation techniques. The control algorithm is implemented on a personal computer using a 386 processor, but it is simple enough to run as one of many tasks on a less powerful microprocessor.
