Abstract
Currently, products manufactured by the winding method are widely used in many industries due to their unique physical and mechanical properties. Due to the improvement of the winding process technology, more stringent requirements for the drives speed and their adaptability to changing operating modes began to be imposed on electrical control systems. This is possible only with the use of modern, digital controls for the winding process. At the same time, it is necessary to have information about the state of the technological process. This information is obtained by using various sensors: tension, belt speed and the length of the winding path. The information from the sensor data is sent to the drive in the form of analog signals, which must later be converted to digital form. The conversion is carried out using analog-to-digital converters. In this paper, model circuits containing time delays and level quantization in analog digital converters used in the electrical engineering system have been developed in the MatLab Simulink package. Using the developed model, the effect of the information delay time during its conversion in an analog-to-digital converter and level quantization on the drive operation was studied. During the study, the delay time varied from 0.1 to 16 ms, and the level of discreteness was from 8 to 16 bits. It is shown that when using modern analog-to-digital converters with a conversion time of 1 ms or less and a bit depth of 8 bits or more, the electrical control voltage system behavior practically does not differ from a system in which there is no level conversion and the signal conversion time is zero.
