Self-identification method of arrangement and effective pressure areas for a vibration-isolation table supported with a redundant number of pneumatic actuators

For the purpose of developing a vibration-isolation table with flexibility and/or scalability (which means “with adaptability to desired load specification”), this study investigates a self-identification method with regard to positions or arrangement and effective pressure areas of pneumatic actuat...
