Recently, active vibration control devices are widely used in many industrial fields. These are categorized into the following two types with their mechanisms. (A) Vibration is controlled by actuators whose one ends are connected to the controlled object and the other ends are connected to "the fixed floor or reaction walls". (B) Vibration is controlled by actuators whose one ends are connected to the controlled object and the other ends are connected to "the movable mass". Typical devices of (A) are active vibration isolation devices. The advantage of type (A) is excellent vibration control performance. However, it is difficult to downsize the devices, because the actuator has to support the controlled object. Meanwhile, typical devices of (B) are active mass dampers (AMD). In type (B), since the actuator doesn't need to support the controlled object, it is possible to realize compact systems. However, the control system design of type (B) tends to be complicated, especially for multi-axis plants. In this paper, we propose a new vibration control system design concept called "Direct Inertia Force Control (DIFC)". By using the DIFC, we can achieve the advantage of the type (A) and (B) simultaneously. Also the DIFC is able to cover the disadvantage of (A) and (B) cited above. Furthermore, the effectiveness of the DIFC is verified by using a newly designed one-degree of freedom active vibration control device, in experiment.
