摘要
为了验证125MN挤压机速度控制系统中的主要速度控制元件大通径节流阀的数学模型、控制策略的正确性、可靠性和实用性,文章对该节流阀特性进行现场调试实验研究,主要是对节流阀的流量特性和阀芯位移动态特性进行调试。
In this article the flow and spool displacement dynamic character were reserched by field-debuging in order to verify the correctness.Reliability and practicability of the mathematical model and control strategy of the large passage diameter of the main speed control unit of the 125 MN extruding machine speed control system.
