摘要

本文旨在发展利用双边控制系统的频域信息识别人和环境阻抗的方法。传统的方法是在双侧控制系统的共模中加入正弦波,但该方法不能在频域提取触觉信息。人体阻抗被认为是瞬息变化的,阻抗识别方法的发展是迫切需要的。本文将低通滤波后的m序列信号加入到双边控制系统中,利用频域信息识别人和环境的阻抗。通过实验验证了该方法的有效性。

Identification of human and environmental impedances by using bilateral control system with low-pass filtered M-sequence signal
This paper aims to develop the method for identifying human and environmental impedances with information in the frequency domain by using bilateral control system. In the conventional method, a sinusoidal wave is added to the common mode of bilateral control system, however, this method cannot extract haptic information in frequency domain. Human impedances are assumed to change every moment, and the identification method of impedance is strongly desired to develop. In this paper, low-pass filtered M-sequence signal is added to the bilateral control system for identifying both human and environmental impedances with information in the frequency domain. Experiments were conducted for verifying the effectiveness of the proposed method.
