Abstract
The ability to determine the actual differential characteristics of motion is important for accurate control of precision equipment. In a feedback loop with an incremental encoder, the accuracy of the obtained differential characteristics of motion decreases with increasing it order. The reason is the errors that are associated with the accuracy of marking and the distortions in the process of measurement signals transmitting. Signal distortion depends on the circuitry, communication interface, cable type and length, the presence of external interference, and the characteristics of the power supply. The study of the influence of these factors on the accuracy of determining the differential characteristics is an important task. In this paper, the permissible values of measurement signal distortions are determined based on the requirements for the accuracy of obtaining differential characteristics up to a jerk. An experimental setup that satisfies these requirements is proposed. The setup allows generating reference measuring signals and examining their distortions. The results of studies of the distortion of measuring signals using an experimental setup are shown. Directions for further research are proposed.
