[Abstract]:One of the key technologies of the internal high pressure forming control system is the simultaneous control of the position of the two sides of the cylinder in the process of internal high pressure forming.The simulation and experimental research is carried out on the multi-variable coordinated control simulation test platform developed by ourselves. The mathematical model of the side cylinder position control system is established, and the "equal master-slave" control mode is adopted.The PID control simulation model of the system is built by using Simulink. The simulation results prove the feasibility of using PID control to carry out the experiment.On this basis, the S7-300 PLC is used as the main controller and the Win CC configuration software is used to carry out the experimental research on the single-side cylinder position PID control and the two-side cylinder position synchronization PID control system. The experimental results show that the PID control system for the two sides cylinder position synchronization is based on S7-300 PLC.The synchronous control accuracy is high and the anti-interference ability is strong. It can meet the control requirements of the position synchronization system of the internal high-pressure forming machine. It provides a reference for the practical application of the S7-300 PLC internal high-voltage forming machine control system.
