Smith-Fuzzy控制器在回转窑温控系统中的应用

An application study of Smith-Fuzzy prediction control on rotary kiln

回转窑是工业生产中用来焙烧某些物料的一种大型设备.目前许多回转窑的控制仍是采用人工经验的方法进行的,控制效果不理想.本文将Fuzzy控制和Smith预估控制相结合,针对回转窑本身具有的大惯性,纯滞后,非线性等特点提出一种新的回转窑控制方法.通过对回转窑控制的仿真分析,结果表明新的回转窑控制方法具有很好的快速性和很小的超调量,能够满足回转窑工艺生产的需要.

Rotary kiln is a bulky facility used to calcine raw materials in the industry.But at present, most rotary kilns are controlled by experienced people .The result of control is always out of acceptance. So a type of Smith-Fuzzy prediction control system on rotary kiln is proposed in this paper. The simulation results show that the system is stable and the control effect meet well the requirement of production.
