Zusammenfassung:
Model and implement a hydraulic system with fuzzy position control of a double acting cylinder and PID pressure control of a hydraulic motor on a plastic extruder. The control system will be implemented with the Festo TP 702 by means of a controller, display, graphical interface and link to Fuzzy control and MATLABTM PID_Tuner to obtain graphs. Modeling provides the process transfer function, proportional control constants and position and pressure control graphs, which are then validated between the WinCC Advanced interface graphs of the physical process implementation with the Festo S7-1200 PLC, generating a graphical comparison of the control of position and pressure variables. This results in an accuracy error of 1% between the result of the modeling and the physical implementation, which is acceptable in an industrial process. The HMI, as well as the SCADA system was performed in WinCC Basic and WinCC Advanced respectively, generating a graphical interface both local and remote in approximately real time. The mathematical modeling of an industrial process guarantees the reliability and optimal behavior of the plastic extrusion process, minimizing production costs and raw material waste.
