| Abstract: | Based on digital pneumatic component named of combined digital valve, the counter-pressure casting control system is developed. Its control algorithm and the factors which have effects on control precision are also studied. Results show that response velocity and control precision of the system are increased by controlling the area and time of the open valve by use of pulse code modulation control algorithm, and the property of the aluminum alloy casting produced by the control system is also improved effectively. |
