A vibration isolation control using electromagnetic spring actuator is presented. The device consists of spring type actuator stacked with iron particles layers, the electromagnet the permanent magnet. When base vibrations occur, the electromagnetic force created by the electromagnet isolates vibration of the top of the permanent magnet which lies on the spring actuator. In general, vibration isolation controls need both the displacements and velocities of the vibrating body. But in this research, vibration isolation controls is possible by using the displacements and velocities of the base. Therefore, this control method is straightforward and compact, because it requires no complex control devices.
