　A free-piston engine linear generator system is expected for use as a high-efficiency generator engine. The cupper loss is decreased using resonant output distribution control which limits the maximum electric current and uses the mover inertia for power dispersion. But this causes iron loss and spring heat loss is larger due to stroke extension. Therefore, we confirmed that the total loss decrease by using its control in the theoreticaly calculation and simulation. Furthermore, the variable damper control is effective for decrease at generation time in using non-linear spring.
