| 摘 要： | 气辅技术能够克服常规注射成型和挤出成型中所固有的缺陷，具有一系列的优点。塑料成型过程中采用气辅技术只需增加一套气辅设备，其技术核心是气体压力控制系统。设计了一个基于多模态智能PID控制器的低压控制系统并进行了软件开发，结果表明，该控制系统可以实现对气压高精度的实时控制，为实现高压控制打下了坚实的基础。

| Abstract: | Gas-assisted technology can overcome many defects existing in normal injection molding and extrusion molding, and it has a series of merits. It needs to add a suit of gas-assisted fixture, and the key issue is the gas pressure control system. A low-pressure control system for gas-assisted molding on the basis of the multimode intelligent PID controller is designed and its software package is developed. The results show that the control system can realize the real-time control of high precision for gas pressure, which makes the stabilized base for high pressure control. |
