人體下肢輔具之系統控制策略

Design and Implementation of Stand Up Assistant System

指導教授 : 張政元

摘要


本論文設計與實踐一種攜帶方便的人體下肢輔具,輔助行動不便的人士之「起身」用途。主要的內容是利用氣墊充氣的原理輔助人體起身,將氣墊放置於座椅下方,利用車用型的打氣機與氣壓元件所組成的模組,並結合壓力感測器判斷人體起身之訊號,達至自動化輔助人體起身。本論文依據氣體組件構造簡單、體積小以及氣壓元件成本便宜等性質作為器材的選用,有利於生活上的可行性與攜帶性。 本論文研究重點為:(1)壓力感測器的判斷分別以微分控制器與比例-微分控制器做為討論與分析;(2)本研究採用不同體重的測試者,測試人體「坐下」至「起身」訊號;(3)實驗結果的部分,主要證明使用者的體重輕重是否影響本研究之設計;(4)以及證明人體坐至椅座上左右晃動與前後移動訊號曲線是否影響本實驗之研究設計。

The study aimed to design a portable lower limb assistive device to assist the elderly to stand up. The theory of air inflation was applied with a mat placed under a seat. At the same time, an air pump for cars and a module with pneumatic components were combined with a pressure sensor to detect the signal of standing up, which resulted in automation of assistance for human body to stand up. The gas components are simple and small, and the pneumatic components are cheap, the characteristics of which are convenient and portable to be used in daily life. The study focused on the following points. The discussion and analysis of differential controller and Proportional - Derivative controller were applied for the detection of pressure sensor. Subjects with different weights were tested for the signals of sitting down and standing up. The study results intended to prove that the user weights and the signal curves of horizontal and back and forth shaking when the user sitting on a chair are factors to affect the design of the study.
