| Research Abstract |
Force redistribution method for compensating actuator-breakdown of vibration isolation tables is investigated in this study. The vibration isolation table is supported by a redundant number of actuators with respect to degrees of freedom of table motion. This study proposed a novel force redistributing method which utilizes redundancy of the actuators. When some of the actuators broke down, their output forces were appropriately re-distributed on the unbroken actuators by the proposed method. So, this study achieved a vibration isolation system with high tolerance to actuator breakdown.
