【摘要】 针对管网叠压供水系统的非线型、大时滞、数学模型难确定的特点,利用模糊算法设计了可进行在线参数整定的FuzzyPID控制器。该控制器能够根据不同的工况选出合适的控制参数,对供水系统中的水压调节进行有效控制。仿真结果表明,采用Fuzzy-PID控制器后,控制系统的动态性能得到有效提高,同时增强了系统的抗干扰能力,具有更好的鲁棒性。更多还原

【Abstract】 A fuzzy-PID control strategy for network pressure-superposed water supply system is proposed,according to characters of system such as nonlinearity,large inertia and pure lag,multivariable coupling.The control strategy can well adapt to the variable model parameters of water supply system has broad application prospect in the water supply system.Simulation results show that fuzzy-PID controller not only improves the system’s dynamic performance.更多还原
