PURPOSE:To promote the reduction of vibration, by detecting a change of torque of an engine and generating torque, which acts suppressing vibration so as to reduce the change of torque, by controlling an actuator to be driven through the result of the detection of the change of torque. CONSTITUTION:A device, which detects a change of pressure in a cylinder chamber by a pressure sensor 19a, obtains a level of changing torque and its generation timing by a detection value of the change of pressure. A signal of this pressure, which is amplified by a pressure gage 20a to an electric signal of predetermined voltage level, is input to a control circuit 21. The control circuit 21 converts this signal by a predetermined control rule into a signal, having a phase and a gain necessary for reducing a change of torque in a Stirling engine 50, to be output to a driving circuit 22. And the driving circuit 22 supplies driving power to an actuator 18 generating vibration suppressing torque for negating the change of torque. Here the changing torque and the vibration suppressing torque generate their phase reversely to each other so that vibration decreases very smaller. |
