摘要:针对纸幅横向定量控制具有多变量、时变、非线性等特点，提出了一种在线自整定模糊PID控制算法，采用模糊推理对PI参数实现自整定。仿真结果表明，该控制算法控制效果优于传统PID控制。结合河北某造纸厂纸幅横向定量控制系统实际应用，控制效果得到很大改善。

Abstract:Aiming at the characteristics of multi-variable， time-varying and non-linearity of cross direction basis weight control of paper web， an on-line self-tuning fuzzy PI control algorithm was proposed.The PI parameters were self-adjusted by fuzzy reasoning.According to the simulation results， the control result of the control algorithm was very much better than traditional PID control.The control effect of a basis weight control system in a paper mill in Hebei province has been greatly improved after using the new method．
