MODELING, SIMULATION AND SCADA-BASED CONTROL OF AN AUTOMATED SHEET METAL TRANSPORT SYSTEM

Abstract

This paper presents the modeling, simulation, and implementation of an automated sheet metal transport system with integrated SCADA control. The proposed system is designed to improve the efficiency and reliability of industrial laser processing by replacing manual handling with an automated solution consisting of transport carts, a pusher mechanism, and a transversal unit with vacuum handling. A programmable logic controller (PLC) implemented in the UniLogic environment is used to coordinate all subsystems, including encoders, inductive sensors, and electromechanical actuators. In addition, a mathematical model of the motion control system is developed and analyzed using MATLAB/Simulink. The control strategy is based on a cascaded structure with an inner loop for speed regulation and an outer loop for position control. The simulation results demonstrate stable system behavior, accurate positioning, and fast convergence to the target position with negligible steady-state error. Furthermore, the SCADA system enables real-time monitoring, data logging, and alarm management, enhancing operational efficiency. The proposed approach provides a scalable and reliable solution for industrial automation, combining control theory, simulation, and practical implementation.
