<p>An externally excited resonant free piston Stirling engine thermal amplifier system which is over damped at all load levels and will not freely oscillate and wherein the displacer/piston system of the Stirling engine is externally driven by a separate drive motor (14). The system includes means for sensing at least one preselected operating parameter of the Stirling engine thermal amplifier (21, 29) and/or the load driven by the Stirling engine thermal amplifier (16) and deriving feedback signals indicative of such operating parameters. The system further includes feedback means responsive to the operating parameter sensed signals and operative to develop control signals for variably controlling the drive motor (14) to thereby precisely, variably and stably control the operation of the Stirling engine thermal amplifier system.</p> |
