摘　　要：球磨机制粉系统具有多变量强耦合、非线性严重、动态特性复杂等特性,数学模型不仅难以建立,而且随着煤的质量差异会发生缓慢变化;在对球磨机动态特性进行分析的基础上,提出了一种新型检测手段和控制策略,运用磨音式智能识别系统代替原有的传感器,控制器采用模糊控制算法,以确保动态响应和稳态精度;实际运行效果表明,改进后系统具有很好的鲁棒性及稳定性。Ball mills are strongly coupled, multivariable, serious nonlinear and have complex danamic characteristics. Its mathematic model is hard to build and changes slowly with the quality of the coal. A new kind of measurement item and control strategy are put forward based on analyzing the dynamic characteristics of ball mills. The sound intelligent recoghition system instead of those existing sensors and fuzzy control algorithms are applied. The actual application shows that the recified system has good robustnes and statibility.
