摘　　要：讨论了闭环控制在气体辅助注射成型过程中的实际应用 ,在气体辅助注射成型过程中 ,得到与保持所需的气体注射压力是成功应用这一过程的关键因数之一。推导出了气体辅助注射闭环压力控制系统的数学模型 ,并用控制系统计算机仿真软件—Matlab的仿真工具箱—Simulink进行仿真。This paper is concerned with the practical application of closed_loop control on the gas pressure during the gas_assisted injection molding process.One of the critical factors for the successful application of the process is the obtaining and maintaining of a desired gas injection pressure.In this paper,the model of pressure control system is derived theoretically and simulation is carried out by means of Simulink of the toolbox of Matlab.The results can be useful for study and design of a closed_loop pressure control system.
