摘　　要：针对双容水箱普遍存在容积延迟问题和传统P I D控制难于达到控制要求的特点,提出了基于串级技术的双容液位模糊PID控制系统。系统根据双容水箱液位控制的特点,采用模糊串级PID控制技术、智能仪表AI808、M C C S组态软件实现了双容水箱液位的高精度控制。实验表明:该系统具有静态精度高、自适应能力强、可靠性好、抗扰动性强等特点,大大提高了水箱液位的控制质量。In order to solve the problem of capacious-lags in double-tanks,the cascade control technologies based on fuzzed-PID algorithm was investigated and it was hard for the traditional PID control to the high stable constant requirements.A new system based on cascade fuzzed-PID control,intelligence appliance and MCGS configuration software was designed to get high stable constant requirements in industrial double-tanks.The results showed that the control system has the characteristics of static accuracy,adaptability,reliability,and anti-interference.And good effects achieved by this controller in the double-tanks.
