【摘要】 城市供水系统具有时滞和非线性特性等特点,仅利用常规PID控制不能使供水系统的各项性能指标很好的满足要求.针对这一实际情况,在双储供水系统中设计了一种模糊技术与常规PID控制算法相结合的模糊PID复合控制系统,该系统能够减少能量浪费,提高水压稳定性.实践运行表明,该系统运行状况良好,性能优越,验证了其有效性和可靠性.更多还原

【Abstract】 Urban water supply system has the characteristics of time delay and nonlinear characteristics,using conventional PID control can not only make each performance index of the water supply system well meet the requirements.Aimed at the actual situation,we designed a fuzzy PID compound control system of fuzzy technology and conventional PID control algorithm combining in the reservoirs water supply system,the system can reduce energy waste,improve the stability of water pressure.Practical operation shows that the system is running in good condition,superior performance,and verifies its validity and reliability.更多还原
