Pneumatic actuators have several advantages for industrial applications, such as, high power/weight ratio, low heat generation in the repeated operation, which is a serious problem for electric motors. However, due to the compliant characteristics of the servo system caused by the air compressibility, it is easily affected by frictional force during position control, making it unsuitable for high-precision application. Ultra-high precision positioning technology has the potential to widely apply pneumatic actuators in precision work and lead to industrial breakthroughs. In this study, we propose a nanometer-order positioning technology using a practical general-purpose pneumatic cylinder sealed with a common rubber gasket, and verify the possibility of industrial application through several experiments.
