摘　　要：研究挤压式供水系统优化控制问题,系统存在控制多变的参数。为保证整个系统稳定运行,通过分析系统管网压力近似数学模型可知,采用常规PID去控制挤压式供水系统,难以保证系统适应控制系统的参数变化,压力始终有较大波动,稳定性差。为解决上述问题,提出了将模糊控制与PID控制相结合的方法,设计了一种参数自整定模糊PID控制器去控制挤压式供水系统,弥补了系统稳定性差的问题。并在MATLAB仿真软件中进行了仿真验证,为供水系统稳定性控制提供了依据。For extrusion type water supply system, it is important to guarantee stable operation of the whole system with. By analyzing the system pipe network pressure,it is shown that the conventional PID control can not guarantee the system to adapt to the variable parameters with approximate mathematical model, the pressure always has great fluctuation, and the stability can not be guaranteed. This paper proposes a new method which combines fuzzy control and PID control, a parameter self- tuning fuzzy PID controller is designed to control the extrusion type water supply system, which can guarantee the system stability. And the simulation in the MATLAB simulation software is carried on.
