模糊控制理论在煤矿通风安全自动化系统中的应用

Application of Fuzzy Control in the Automation System of Mine Ventilation

由于煤矿通风系统的独特性和复杂性 ,要精确地建立具有时滞及控制对象的数学模型遇到较大的困难 ,因此 ,人们寻求了一些新的解决途径。笔者基于模糊控制理论 ,并提出将其应用于煤矿通风自动化系统中 ,同时采用单片机来实现模糊控制 ,实践证明 ,此法取得良好效果 ;与常规的控制方法相比 ,模糊控制方法具有响应快、控制简单、不需建模等特点 ,适用于矿井通风自动化系统 ;笔者还讨论了调节窗模糊控制系统设计 ,系统的单片机实现及软件编制 ,并进行了实验及实验结果分析 ;最后提出了向自组织方向的深化方案。

The mine ventilation system has its own performance. It is very difficult to precisely setup a mathematical model for controlled object and time lag. In this paper, a new automation system is provided, in which the fuzzy control principle is applied, and computer is used. Comparing with the routine algorithm, the fuzzy control method shows the characteristics of quick to response, easy to control, and needless to establish a model. It is feasible to be used in mine ventilation system. The design of the regulation window, the application of PC, and the development of its software are also discussed. The result is exemplified by experiments. Finally, a protocol of self organization is put forward.
