【Abstract】 Based on the digital pneumatic component named the combined digital valve, the counter-pressure casting control system was developed, 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 by controlling the area and time of the open valve using numerical increment control algorithm, and the property of the aluminum alloy casting produced by the control system was also improved effectively.更多还原
