从物理角度出发，建立了一种注射成型动态模型，用于选择热塑性注射成型填充阶段压力控制的PID增益。通过实验确定了模型各方面和特定物理参数值的相对重要性。采用极点-零抵消法和根轨迹法选择控制器增益，获得了良好的控制性能。对开环和闭环系统的响应进行了预测和验证，总体上具有良好的一致性。
A dynamic model of injection molding developed from physical considerations is used to select PID gains for pressure control during the packing phase of thermo-plastic injection molding. The relative importance of various aspects of the model and values for particular physical parameters were identified experimentally. The controller gains were chosen by pole-zero cancellation and root-locus methods, resulting in good control performance. Both open and closed-loop system responses were predicted and verified, with good overall agreement.
