多道前臂肌电信号集中参数模型系统的确定

Determination of AR Parameters for Multi channel Upper Limb EMG

采用了分段的ＬＳ方式来提取前臂肌电信号集中参数模型ＡＲ 系数，在此基础上，对不同时窗、不同的采样频率以及不同的衰减系数的作用进行了比较，得出最佳的选择。与目前其他ＡＲ 系数的提取方法相比，实验结果表明分段的ＬＳ方法有着更好的辩识效果。

In this study, a segment LS method was used to determine the AR parameters for multi channel upper limb EMG. Different sampling frequencies, time windows and attenuation factors were tested and an optimum selection was obtained. According to the experiment result, the segment LS algorithm should be the best method compared with others.
