【摘要】：内高压成形过程中两侧缸位置同步控制问题,是内高压成形控制系统的关键技术之一。应用自主研制的多变量协调控制模拟试验平台进行仿真与试验研究,对侧缸位置控制系统建立数学模型,采用"同等+主从"控制方式,利用Simulink搭建该系统的PID控制仿真模型进行仿真,仿真结果证明了采用PID控制进行试验的可行性。在此基础上采用S7-300 PLC作为主控制器,基于Win CC组态软件,进行单侧缸位置PID控制及两侧缸位置同步PID控制试验研究,试验结果表明:基于S7-300 PLC的两侧缸位置同步PID控制系统,同步控制精度高、抗干扰能力强,能够满足内高压成形机位置同步系统控制要求,为S7-300 PLC在内高压成形机控制系统上的实际应用提供了参考。
[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.
