Abstract

In the control process of transfemoral prostheses in real time, the need to solve a number of non-trivial tasks there arises. The most difficult of them: recognizing the intentions of the disabled person to carry out any movement in the short term and choosing the optimal strategy for moving to the target, taking into account excessive number degrees of freedom of the prosthetic system. At the same time, the optimal should be considered the strategy of movement, which ensures the safety and most comfortable walking of a disabled person from its subjective point of view. Such a strategy can be implemented in a frame of the intellectual-synergistic concept of control. Herewith, the prosthesis control system is designed based on two basic subsystems: the intellectual subsystem - designed to assess the current state and recognize the intentions of the disabled person and the synergetic subsystem - designed to select the optimal strategy for limb movement toward the goal. In this work, the structure of the transfemoral prosthesis control system, realized within the framework of the intellectual-synergistic concept with regard to synergistic quality criteria, is substantiated. It is shown that the use of reasonable synergetic quality criteria allows successfully solving the pseudo-Bernstein problem when planning the movements of controlled transfemoral prostheses and using these movements as reference for the prostheses control system.
