| Abstract: | The fluid surface forcing control system applied on counter pressure casting is built based on the combined digital valve as the main flow control component. Its control algorithm and the factors which have the effects on the control precision have also been studied. The results have been shown that the response velocity and control precision of the system were increased apparently with the application of the digital valve and the main factors which affect the control precision and response speed are the digital and control algorithm. |
