Elman神经网络在表面肌电连续估计肘关节角度中的应用
Application of Elman neural network in continuous estimation of elbow joint angle with sEMG
摘要
Abstract
Objective: To estimate the elbow joint angle and improve the rapidity and precision of the model. Methods: The elman neural network (ENN) based on surface electromyogram (sEMG) was established and investigated. The sEMG signals were collected by the electrodes placed on the skin surfaces of biceps muscle (BM) and triceps muscle (TM), and the actual elbow joint angle was recorded by an inertial measurement unit (IMU). Results: Theoretical analysis indicates that the ENN is feasible to be employed for estimating the elbow joint angle. Experimental results and the parameter discussion based on the model order and the number of hidden layer neurons further indicate that the minimum RMS error of ENN is 18.1899 degree. Conclusion: The RMS error is controllable when the ENN is used to estimate the elbow joint angle under the optimal parameter. Theoretical analysis and experimental results shows that the ENN is effective in estimation of joint angles.关键词
