基于触滑觉感知的智能假肢抓握控制方法研究

摘要:

【】触觉和滑觉感知功能是仿生假手不可或缺的感知功能。本文在原有智能假肢的基础上,通过对触滑觉感知方法的研究,包括触滑觉传感器的选型、后续测量电路的设计和测点布局分析等,开发了一种可以同时实现触觉和滑觉感知的智能假肢。进而,通过模糊逻辑控制方法的引入,实现了假肢的可靠抓握功能及抓握保持过程中的自适应响应控制。实验结果表明,该智能假肢可以实现假肢抓握的稳定控制,并在被抓握物体产生滑动时进行精准快速的自适应响应控制。

Abstract:

Perception of tactile and slide sensing is an essential function for bionic prosthetic hand. On the basis of original intelligent prostheses, this paper designed an intelligent prosthesis that achieving tactile sensing and slide sensing through the study of tactile and slide sensing methods, those studies included selection of tactile and slide sensor, design of measuring circuit and analysis of the distribution of measuring points, etc.. Further, it achieved the reliable gripping and the adaptive response controlling during maintaining gripping through introducing the fuzzy logic control method. The results showed that this intelligent prostheses achieved stable control of gripping, and fast and precision adaptive respond control while the object sliding.
