基于模糊PID算法的同步柔性冲压装置控制系统研究

Research on control system of synchronous flexible punching device based on fuzzy PID algorithm

  • 摘要: 同步控制系统是多边同步柔性冲压装置的关键部分,其性能的优劣直接影响产品的质量,而液压同步系统因非线性摩擦、偏载以及运行参数的时变等影响,对其建立精确的数学同步系统模型非常困难。针对这一问题,利用Simulink和AMESim仿真软件的优势,搭建同步控制系统的联合仿真平台,采用含补偿因子的双重模糊控制方法来有效解决这一问题。在同一工况下,相比于传统液压控制系统,带补偿因子的双重模糊PID控制可以更好地达到同步控制的精度要求,而液压控制回路也能够实现节能的目的,实现了零部件三边定心冲压的高精度化,可有效减少不合格品的产生,提高生产效率。

     

    Abstract: The synchronous control system is a key part of the multilateral synchronous flexible stamping device. Its performance directly affects the quality of the product. The hydraulic synchronous system has established precise mathematics due to the influence of nonlinear friction, eccentric load, and time-varying operating parameters. It is very difficult to synchronize the system model. In response to this problem, the advantages of Simulink and AMESim simulation software are used to build a joint simulation platform for the synchronous control system, and a dual fuzzy control method with compensation factors is used to effectively solve this problem. Under the same working conditions, compared with traditional hydraulic control systems, the dual fuzzy PID control with compensation factor can better achieve the accuracy requirements of synchronous control, and the hydraulic control circuit can also achieve the purpose of energy saving and realize the three sides of the parts. The high precision of centering stamping can effectively reduce the generation of unqualified products and improve production efficiency.
