摘要

The article studies the possibility of using the LabVIEW programming environment to develop real-time dynamic models of continuous processes. The principle of data flow implemented in the LabVIEW environment makes it possible to abandon the direct solution of differential equations when developing a dynamic simulation of a technological object. It is proposed to present the simulation object as a set of dynamic elements, the main of which is the integrating element. The block diagrams of the proportional, integrating, inertial, and delay elements are given. The applicability of the LabVIEW platform for modeling continuous processes is demonstrated on the example of a simple heat exchanger model, which hydrodynamic flows structure corresponds to the ideal mixing model. The schematic and block diagrams of the developed model are given. In order to test the heat exchanger model, a numerical experiment was carried out in static and dynamic modes. The results of testing of the model confirmed its consistency, sensitivity and validity, which are signs of adequacy.
