The application research of MR damper in intelligent bionic leg

MR damper is a new-style intelligent damper and is newly applied in intelligent bionic leg. The conception and research purpose of intelligent bionic leg was introduced. Modeling methods of MR damper were discussed and modified Sigmoid model was proposed. Then experimental modeling was introduced in detail. In the end, the simulation of intelligent bionic leg using iterative learning control was done. The results indicate the intelligent bionic leg with MR damper can track the normal gait of human healthy leg well and has good humanoid characteristic.
