摘　　要：恒压变频供水技术在供水行业广泛应用,并取得了很好的经济和社会效益。对于生活小区以及高层建筑供水来说,常常由于管网的非线性、控制系统本身的结构复杂而难以用经典的控制方法来解决。为此结合某小区实例阐述了一种带模糊策略的控制方法,详细介绍了设计思路及程序。实际运行表明,改进的控制系统效果良好,克服了原系统压力不足及压力不稳等缺陷。The frequency conversion constant pressure water supply technology is widely used in water supply field, and good economic and social benefits are obtained. However, classical methods are difficult to control water supply of residential areas and high-rise buildings due to non-linear network and complex structure of control system. Therefore, an intelligent control method with fuzzy theory expounded with a residential area example, and the design idea and control program were introduced in detail. The real operation shows that the improved control system has good efficiency, and the disadvantages of pressure shortage and unsteadiness in the original system are overcome.
