| 摘 要： | 在采用电阻法直接测控碳势的方法中,提出了一种分段参数调节增量式PID算法,通过实际调试和理论推导表明,渗碳工艺过程控制具有控制超调量小、过渡时间短、精度高、软件实现方便等优点,稳定后碳势控制精度可达±0.03%。

| Abstract: | In this paper, a PID calculating method with the mode of increment and staged parameters regulation is provided for the Resistance Method for direct measuring and controlling carbon potential. It has been proved by practice that such a method has the advantages of little over control, short transient time, high accuracy and convenient software. |
