智能控制在柴油机低温冷起动上的应用仿真

Analog Study on Intelligent Control Applied to Cool-Starting at Low Temperature for Diesel Engines

用分级递阶智能控制原理对柴油机低温冷起动的两个难点进行研究 ,设计出相应的分级递阶智能控制系统 .系统分为智能监控中心和自动控制单元两级 ,采用 RS- 2 32接口将这两级结构连接 ,实现二者之间的数据交换 .仿真实验表明 ,系统能使被控对象——柴油机低温冷起动加温装置正常运行 。

The principle of hierarchically intelligent control was used to study the two difficulties of cool starting at low temperature for diesel engines. And the corresponding hierarchically intelligent control system based on the principle was designed. The system is composed of intelligent control center and automation unit. Interface RS 232 was used to interchange dada between these two parts. The analog experiment shows that the system can ensure working normally for the controlled object, heating equipment, and the anticipative aim is achieved.
