EXAMINATION OF THE POTENTIAL FOR CONTROLLING THE TRACTOR'S DRIVE WHEEL'S TURNING ANGLE WITH ENCODERS
Abstract
This article analyzes the operating principles of encoders used to convert linear and rotary motion into digital signals. Particular attention is given to the working mechanisms of optical and magnetic encoders, as well as the structural and functional features of incremental and absolute encoders. The main advantages of incremental encoders include simple design, high resolution, and low cost, while their primary limitation is the relative measurement principle and the loss of positional information when power is interrupted. The study also examines the structure of coding disks, encoding methods based on Gray and Barker codes, and the advantages of absolute encoders in high-precision control systems. The comparative analysis demonstrates the practical significance of encoder technologies in modern industrial automation and motion control applications.
