摘　　要：将鲁棒性强、超调小、响应速度快、易实现的PDF控制方法运用到电炉电极系统的控制上,其中在电极控制系统的设计方面,采用双闭环模式——速度环作为内环,电极的电流环作为外环。并对PID控制和PDF自适应控制进行了仿真,仿真结果表明PDF自适应控制优于PID控制。The PDF（pseudo-differential feedback） control method which boasting of strong robustness,small over-correction,fast response and easy implementation was applied to electric arc furnace electrode control system.The control system design adopted a double closed-loop mode of taking speed loop as inner ring and the electrode current loop as outer ring,and having both PID control and PDF adaptive control simulated.Simulation results show that the PDF adaptive control outperforms the PID control and other traditional methods.
