Desenvolvimento de um simulador virtual interativo de uma bancada de válvulas de controle em arquitetura Web

Abstract

The alternation of physical experimental laboratories to virtual simulation environments has emerged as an increasingly attractive possibility in view of the high costs of acquisition and maintenance of real didactic plants. The present research brings an approach to how a computer simulator based on a single page web architecture (SPA) can faithfully reproduce the dynamics of hydraulic processes and validate closed-loop industrial control algorithms. The objective was to develop and validate a prototype of a virtual and interactive simulator of a valve flow control bench, using JavaScript programming and an interface inspired by industrial SCADA systems. The research is classified as a technological development of an applied nature focused on software engineering, in which a deterministic numerical resolver was structured based on the laws of conservation of mass and the equations of the IEC 60534 standard. The system synchronously emulates two dynamic sampling routes: the continuous response of the MATLAB/Simulink environment and the discrete temporal scanning and bit quantization behavior of a Siemens S7-1200 Programmable Logic Controller (PLC). The results indicated that the algorithmic stability of the parameterized hydrodynamic model under nominal data from commercial catalogs, which allows the analysis of transient flow regimes in real time through dynamic graphs generated by the Chart.js library. The object-oriented architecture added modularity to the interface, enabling instant switching between linear actuator curves, equal percentage and on/off without numerical divergences in the browser. It was concluded that the simulator rigorously meets its pedagogical and technological purpose, reaffirming itself as a portable, safe and self-sufficient instructional platform for the validation of classic PID control strategies in engineering.
