基于模糊控制的恒压供水系统的研究

摘要

The constant pressure water supply system is a single input, single output, single loop nonlinear control object.The water pressure of the water supply network is an important index of the safe and stable operation of the water supply system, and it is an important part of the automatic control system.After years of theoretical research, a variety of control strategies has formed.However, due to the inertia of the system lag, nonlinear, timevarying characteristics, the use of traditional control theory can't achieve the ideal control quality.Based on fuzzy control mechanism, this article proposed a fuzzy PID controller which was applied to the constant pressure water supply control system, to improve the quality of water supply system control.%恒压供水系统是一个单输入、单输出、单回路的非线性控制对象.供水管网的水压是供水系统安全、稳定运行的重要指标,是自动控制的重要环节.经过多年的理论研究,目前已形成多种控制策略.但由于系统存在惯性滞后性、非线性、时变等特点,采用传统的控制理论无法取得理想的控制品质.文章基于模糊控制的机理提出了一种模糊PID控制器,应用于恒压供水控制系统,以改善对供水系统控制的品质.
