Embodiment 1
[0052] The present embodiment uses an injection molding process to specifically illustrate the method of the present invention. The injection molding process is the process of converting plastic pellets into various products, which mainly includes three stages: injection molding, pressure holding, and cooling molding. In order to ensure the quality of the products produced by the injection molding process and the production efficiency of the products, the relevant process variables should be required to change as much as possible according to the desired set values in each production stage. In the production process, since the injection speed has a great influence on the quality of the final product, it is necessary to control the injection speed with high precision in the injection molding stage, and the corresponding variables should be controlled to a given set value. The injection velocity response of the proportional valve can be identified as an autoregressive model: ...
