Abstract
A Stirling engine feedback controller is provided that includes a Stirling engine having at least one piston, where the Stirling engine includes an Alpha-Stirling engine, and a Gamma-Stirling engine. The feedback controller includes a power sensor, a computer, and an electronic feedback loop. Here, the power sensor is configured to sense the power of the Stirling engine then output a power signal. In one aspect, the computer can be a central processing unit (CPU), or a field programmable gate array (FPGA), where the computer operates a control algorithm. Further, the electronic feedback loop receives the output power signal and an output signal from the computer, where an output signal from the electronic feedback loop is configured to a control a position of the piston(s).
