针对双容水箱普遍存在容积延迟问题和传统PID单回路控制难于达到控制要求的特点,提出了基于串级技术和PLC控制器的双容液位控制系统。系统根据双容水箱的数学模型,采用微分先行的串级控制技术、PLC控制器、MCCS软件组态实现了双容水箱液位的高精度控制和实时显示。实验结果表明：该控制系统具有静态精度高、自适应能力强、可靠性好、抗扰动性强的特点,大大提高了水箱液位的控制质量。

Aiming at the problem of capacious-lags in double-tanks,it was hard for the traditional PID control to the high stable constant requirements and cascade controlling could solve them.A new system based on cascade control of previous difference and PLC was investigated in industrial double-tanks.And this liquid-level control system used the previous difference algorithm of cascade controller,PLC and MCCS was designed according to the mathematical model of double tank.The results show that the control system has the characteristics of static accuracy,adaptability,reliability,and anti-interference,and good effects are achieved by this controller in the double-tanks.
