Title:
PRECISE CONTROL MEANS FOR PNEUMATIC ACTUATOR
Document Type and Number:
WIPO Patent Application WO/2022/108045
Kind Code:
A1
Abstract:
The present invention relates to a precise control means for a pneumatic actuator. Specifically, a precise control means for a pneumatic actuator (1) comprises: a precise location-based displacement control unit (100) for controlling the location of a piston of a pneumatic actuator on the basis of information measured by a displacement sensor (S1) in real time; and a precise weight-based displacement control unit (200) for controlling the location of the piston of the pneumatic actuator on the basis of information measured by a weight sensor (S2) in real time, so that pneumatic pressure supplied into the actuator can be precisely controlled. Therefore, the present invention is advantageous in that pneumatic pressure can be precisely controlled as described above, so that a precise and stable test can be conducted through a test device using the pneumatic actuator.
