| 摘 要： | 鉴于液位过程控制系统是时变、非线性、多干扰的复杂系统,因此通过对过程控制装置中双水箱液住系统的分析,建立相应控制策略,提出采用PID模糊镇定算法,并基于MATLAB仿真和MCGS组态软件进行相关应用实现．仿真和应用实现效果均表明：采用模糊PID控制的下水箱液位较常规PID控制具有响应速度快,且能较快地达到稳定,从而改善系统的性能．

| Abstract: | The water level system of double tanks is analyzed as a time-variant, non-linear and multi-disturbance complex system. In this work, the control model is constructed and fuzzy self-tuning PID control is presented. Simulation results using MATLAB and MCGS software show that the water level controlled by the Fuzzy self-tuning PID controller can response fast and reach the stable state as quickly as that controlled by the conventional PID controller. |
