1. A propulsion and braking system using a clutch, the system comprising:
a device including a clutch operation pressure-regulating valve, and the clutch and gears which are configured to control a driven body and a driving body to rotate in a same direction and in opposite directions; and
a control unit configured to regulate a rotational speed of the driven body to enable a continuous operation at a speed that is lower than a rated rotational speed using a slip of the clutch, and perform control so that engagement timing control of the clutch and engagement of the clutch are sustained if the driven body requires operation at the rated rotational speed or higher,
wherein, when a braking signal is inputted into the control unit during propulsion of the driven body, the control unit removes an operation pressure of the clutch that is embedded in the device and is in operation, activates the clutch for reversing a rotational direction of the driven body, and regulates the operation pressure of the clutch by the valve to enable braking of a propulsive body, and
wherein the control unit regulates time required for propulsion and braking by regulating an operating time of the valve with a change gradient of a rotational speed set point.
