MODELING OF CONTROL ALGORITHMS POSITIONING OF THE CONSTRUCTION PRINTER PLATFORM

Abstract

In the construction industry, the use of radial-type construction 3D printers is becoming more and more popular. These innovative printers are already successfully used in five countries of the world. They make it possible to reduce the costs of human, energy and time resources, compared to traditional construction methods. Radial printers are compact and do not require additional frame structures. The quality and speed of construction depend on the performance of the printer and the accuracy of its positioning. Researchers are actively working on improving these parameters in order to improve construction results. Platform lift height control plays an important role in achieving high printer positioning accuracy, taking into account build quality requirements. Advanced information technologies, such as simulation modeling and automated control, are used to effectively solve these tasks. The results of experiments and research are used to improve the functional characteristics of the lifting system of the construction printer and can be applied in the development of control systems for other lifting mechanisms, such as a hydraulic lift, a hydraulic press or a telescopic loading crane. The main goal of the research is to increase the accuracy of the positioning of the construction printer platform under conditions of disturbances. As part of the work, the technological parameters of the control object were analyzed, the requirements for regulators were formulated, a simulation model of the lifting system was developed, and the regulators of the platform positioning model were adjusted. The result of the study is the elaboration of the method of structural parametric synthesis of control devices by positioning the construction printer platform.
