| Abstract: | Based on analyzing limitations of the existing electro-hydraulic control system for 7 500 kN die-casting machine, the former control system was reconstructed, accordingly, a digital PID controller was also designed, which was used as a proofread model for the servo control system. The updated control system can effitiently improve the machine’s performances, during its technics process of shot and pressurization. |
