Abstract

To control a free piston linear compressor a cycle of increasing power to the stator, detecting piston collisions and backing off the power input to the stator, is employed to get the best performance out of the compressor whilst limiting piston collision disturbances or damage. In particular the cycle includes gradually increasing the input power to the compressor and perturbing the increasing power by also superposing periodic transient increases in power whilst monitoring the compressor for piston collisions. When "soft" piston collisions are detected, the input power is decremented to avoid continued collisions at the increased power.
