摘要 | Human motion estimation by surface electromyogram (sEMG) is one of the most important human intention recognition methods for active rehabilitation training. This paper proposes a back propagation (BP) neural network and autoregressive (AR) model based real-time sEMG-joint angle estimation method. To reduce the time delay, a moving Butterworth filtering method is designed to filter the lower limb multi-channel sEMG signals. Then correlation analysis between sEMG signals and joint angles is made to reduce redundant channels. A first-order BP neural network is used to build the mapping relationship between multi-channel sEMG signals and joint angles, then the approximated angle by BP model is adjusted by the AR de-noising model, which describes the angle variation features of the given training mode to improve the accuracy and continuity. To validate this method, five able-bodied subjects participated in cycling exercise experiment, and the angle estimation results show that this method presents a good performance on real-time computation, accuracy and continuity. |
