为了进一步提高四辊轧机液压AGC系统的厚度控制精度，将传统的PID控制与模糊控制相结合，设计了一种参数自调节的模糊自适应 PID控制器。该控制器通过分析偏差和偏差变化率，利用模糊逻辑实现PID参数在线自动调节。经MATLAB仿真表明，其控制效果优于传统的PID控制，具有良好的动、静态特性及较强鲁棒性。

In order to improve the thickness control precision of hydraulic AGC system in four-high mill ,the combination of PID control and fuzzy control was put forward and a fuzzy self-adjusted PID controller was built . According to the error and its derivative ,the online self-adjustment of PID parameters was realized using fuzzy logic .The results of simulation indicate that the fuzzy self-adjusted PID is better than the conventional PID ,has the better dynamic and steady property and the stronger robustness .
