英文摘要In this paper, a new technique for predicting human lower limb periodic motions
from multi-channel surface ElectroMyoGram (sEMG) was proposed on the basis of leastsquares support vector regression (LS-SVR). The sEMG signals were sampled from seven
human lower limb muscles. Two channels sEMG were selected and mapped to muscle activation levels for angles estimation based on cross-correlation analysis. To deal with the time
delay introduced by low-pass filtering of raw sEMG, a
k-order dynamic model was derived
to represent the dynamic relationship between the joint angles and muscle activation levels.
The dynamic model was built by data driven LS-SVR with radial basis function kernel. The
inputs of the LS-SVR are muscle activation levels, and the outputs are joint angles of the hip
and knee. In experiments, 48 sEMG-angle datasets sampled from six healthy people were
utilized to verify the effectiveness of the proposed method. Result shows that the human
lower limb joint angles can be well estimated in different motion conditions.
