| Abstract: | Motion state recognition is crucial to the control of intelligent lower limb prosthesis.Taking advantage of the features of EMG,leg angle and plantar pressure,multi-mode and gait phase recognition of lower limb prosthesis was studied.Acquisition system of lower limb was established to get the multi-source motion information.Firstly,features of EMG were extracted by wavelet packet energy,and several HMMs were established to recognize the motion modes of lower limb.Then based on leg information and plantar pressure processed by threshold method,gait phases were analyzed by the fuzzy rule.The experimental results show that multi-mode and gait phase recognition of lower limb is recognized effectively,and the superiority of utilizing multi-information is validated. |
