    摘要: A controller for a free piston generator that is capable of more accurately controlling the behavior of a piston than conventional controllers is provided. During power generation of a free piston generator 10, a controller 18 controls the amount of power generation to cause the velocity of a piston 14 to reach a first velocity command value (for an expansion stroke) and a second velocity command value (for a compression stroke) by electric braking. During motoring, the controller 18 controls the amount of power supply to cause the velocity of the piston 14 to reach the first and second velocity command values. The controller 18 sets the first and second velocity command values by setting first and second velocity command values for a certain round-trip period based on a top dead center position and a bottom dead center position of the piston 14 for the previous round-trip period.
