A Study on Control and Measurement of a Power-Assisted Chair

摘要

A power-assisted chair using pneumatic system has been studied by the authors. The chair aims to help the user to stand up with assistance force generated by a pneumatic cylinder. In this study, a pneumatic cylinder, control valves, a compressor, a microcomputer and electric power sources are integrated in the chair. Control and measurement techniques using the microcomputer are described in this paper.
