Mathematical Modeling of DC Motors for the Construction of Prostheses BT - Advances in Intelligent Systems, Computer Science and Digital Economics

Abstract

The article describes static and dynamic characteristics of a DC motor with independent excitation by mathematical modeling in MATLAB environment for the possibility of further construction of models of electric drive systems with this engine type. The tasks of designing bionic prostheses require solving the problem of developing a control system for this prosthesis. This complex system includes many different subsystems, in particular, DC drive systems. This study examines the control of the knee module of a bionic prosthesis based on a hydraulic cylinder, which is controlled by turning the spool, which in turn determines the moment of resistance. Therefore, the speed of the electric motor is a key factor in the operation of the bionic knee module. Inadequate assessment may result in personal injury.
