Abstract
A sliding mode biomimetic (BSM) controller for a prosthetic device, such as a prosthetic hand, includes an input classification component that receives electromyogram (EGM) signals from two or more electromyogram (EGM) sensors that are positioned on an amputee's body. The input classification component compares the EGM input signals based on predetermined activation threshold values and identifies an input class to determine the amputee's intended movement of the prosthetic device. A finite state machine utilizes the current position of the prosthetic hand and the identified input class to identify the coordinates of a lookup table to determine the next state or position of the prosthetic device. As a result, the biomimetic controller is able to simultaneously control two or more degrees of freedom (DOFs) or functions of the prosthetic hand using only two EGM input signals.
