In article the control system of a bionic prosthesis is considered. In particular, the problem of recognition and finger identification on electromyogram (EMG-signal) is considered. The principle for obtaining the EMG-signal from the bioactive parts of the hand with the help of electrodes placed on an elastic cuff is shown. For creation of base of features it is offered to use the characteristics, the fractal dimensions received by a method. The system of recognition is executed in the form of the fuzzy logic controller. This allows you to more precisely identify the EMG signals and get the highest level of recognition. Experimental verification of the algorithm showed that the proposed recognition method is workable. Also in article the questions of a design of bionic prosthesis are raised – namely, the construction of its kinematic model. The solution is carried out using a coordinate system with the Denavit-Hartenberg parameters, for which constructed the corresponding transition matrix.
