The monograph, "Research and Development of Control Algorithms for Bioprostheses of the Human Body (for example, Prosthetic Hand)," explores the intricate intersection of biosignal processing methods and the challenges encountered in limb prosthetics, with a specific focus on the prosthetic hand. The work is organized into three comprehensive chapters, each addressing critical aspects of this multidisciplinary field. In Chapter 1, an extensive overview of biosignal processing methods is provided, shedding light on the theoretical foundations of myogram processing and addressing contemporary challenges in limb prosthetics. Chapter 2 delves into the analysis of methods and algorithms for processing biosignals that facilitate hand movements. Specific attention is given to the application of the window-amplitude algorithm in upper limb prosthetics, methods of controlling upper limb prostheses, and an exploration of the dynamics of hand movement. Chapter 3 focuses on the development of algorithms and the structural control scheme for a robotic arm prosthesis. This includes the formulation of algorithms tailored for a robotic prosthetic arm, the selection of a suitable hardware platform.
