Background. The object of the study are bionic prostheses of the lower limbs, as close to the design as possible to the amputated limb, for the control of which bioelectric signals appearing in muscle cells and read from the stump muscles are used. The subject of the study are methods and algorithms for controlling the prosthesis of the lower limb. The aim of the work is the development of an information and measurement system for the control of bionic prostheses of the lower extremities, which makes it possible to recognize the signals of muscle activity and to adapt to the specific patient.
Materials and methods. To solve the set tasks, the methods of structural and functional analysis, the main provisions of the theory of automatic control, were used in the work.
Results. A block diagram of the bionic prosthesis control system is proposed, which is characterized by simplicity of adjustment, increased reliability, convenience of use.
Conclusions. The use of the proposed system in domestic prostheses with will make it possible to replace the lost extremity lost as a result of amputation with significantly lower costs compared to foreign samples.
