新型恒压供水系统

针对地区城市水厂供水管网普遍存在铺设复杂、传输距离远、控制对象具有大滞后、强耦合、非线性、参数时变等特点,综合考虑目前供水系统注重管网压力而轻视水库水位等问题。文中提出基于智能神经网络的可调整修正因子模糊PID控制算法进行双闭环控制,使得供水系统不仅能按照模糊控制规则对不同供水工程进行调节,并且能够实时调节PID参数,使系统输出稳定。

The New Water supply System of Constant Pressure Control

After some investigation to a region city waterworks, aiming at its complex water supply pipe laying, long transmission distance, control object has a large, strong coupling, nonlinear, parameters and it is difficult to establish an effective mathematical models, and other characteristics, and because the water supply systems are often focus on supply pressure but overlook the reservoir level, this paper put forward a double-loop control based on neural networks adjusted fuzzy PID algorithm, using intelligent neural networks and fuzzy control application to traditional PID control.The purpose is to educate not only water supply system can be in accordance with the rules on fuzzy control to adjust different water supply project, but also educate real -time PID parameters, making the system output stability..
