A Stirling cycle machine control system includes an energy converter having a moving member. A detector is operatively associated with the moving member. The detector is configured to detect stroke of the moving member. A converter circuit is coupled with an output of the energy converter and is operative to convert output from AC to DC. A regulator is coupled with the converter circuit and a useful load, and is operative to regulate DC voltage. A controllably variable load member is coupled to the converter circuit and is operative to adjust load to the energy converter. Adjustment of the load to the energy converter regulates power output of the energy converter which in turn controls movement of the moving member. Control circuitry is signal coupled with the detector and the load member. The control circuitry is configured to receive a feedback signal correlated with the detected stroke of the moving member. The control circuitry is operative to dynamically adjust load on the energy converter to limit stroke of the moving member below a threshold level. A method is also provided.
