摘要： PROBLEM TO BE SOLVED: To avoid destructive collisions. SOLUTION: In a free piston machine, initial collisions of the piston with structures at the end of the cylinder are detected and generate a change in the magnitude of a perturbation signal, which is applied to the summing junction of a closed loop feedback control system controlling a piston force. The change is applied in a direction to reduce piston amplitude. In embodiments in which maximization of piston amplitude is desirable, the magnitude of the perturbation signal is also varied in the opposite direction in the absence of collisions to increase piston amplitude of oscillation so that operation then hunts between initial nondestructive collisions and a non-colliding maximum amplitude of piston oscillation.

摘要： Multiple free -piston Stirling (FPS) machines are arranged in a group and connected for preventing or minimizing vibration. A first set of identical beta FPS machines are rigidly connected together, arranged in a mechanically co-directional orientation and configured to reciprocate in thermodynamically synchronous reciprocation with each other. The first set has axes of reciprocation intersecting a first point, which may be a point at infinity. The axes of the first FPS machines make the same angle with a central axis of motion and are equi-angularly spaced around the central axis. A second set of beta FPS machines are rigidly connected together and rigidly connected to the first set of machines. The second set of machines are arranged in a mechanically co-directional orientation that is the same as the mechanical orientation of the first set of beta FPS machines. The second set of machines are configured to reciprocate in thermodynamically synchronous reciprocation with each other but in thermodynamically opposed reciprocation to the first set. The FPS machines of the second set are identical to the FPS machines of the first set and have axes of reciprocation intersecting a point, which may be a point at infinity. The axes of the second set of FPS machines all make the same angle with the central axis of motion and are equi-angularly spaced around the central axis of motion.

摘要： Vibrations at harmonic frequencies are reduced by injecting harmonic balancing signals into the armature of a linear motor/alternator coupled to a Stirling machine. The vibrations are sensed to provide a signal representing the mechanical vibrations. A harmonic balancing signal is generated for selected harmonics of the operating frequency by processing the sensed vibration signal with adaptive filter algorithms of adaptive filters for each harmonic. Reference inputs for each harmonic are applied to the adaptive filter algorithms at the frequency of the selected harmonic. The harmonic balancing signals for all of the harmonics are summed with a principal control signal. The harmonic balancing signals modify the principal electrical drive voltage and drive the motor/alternator with a drive voltage component in opposition to the vibration at each harmonic.
