电弧炉电极升降液压伺服系统数学模型建立

Established Mathematical Model of EAF Electrode Lift and Low Hydraulic Servo System

电弧炉在实际工作过程中,电极位置与电极电流的关系为显著的非线性关系。运用经典控制理论,通过建立数学模型对电弧炉的参数进行最佳调整,从而实现电弧炉的PID控制。该控制方法可实现电极位置的控制,从而将电弧弧长控制在某期望值。

The electrode position with the current relationship appeared a notable nonlinearly in the actual work. Through the establishment of a mathematical model, using key control of the theory to make the parameter of are best, which achieve the PID control of EAE The method can realize the location control of the electrode, so that can make the length of arc keeping in an expectation.
