摘　　要：针对水监测系统中流量控制具有非线性、时变性以及不确定性,采用普通PID难以实现其良好的控制作用。设计了一种基于PLC的模糊自整定PID控制器,根据偏差和偏差变化率来实时调整参数,明显改善了系统的动态性能和静态性能,并且采用先进的GSM组网技术,满足了系统数据传输实时、高速与高可靠性要求,以及水量测量与闸位开度信息收集与传输的需要。Aim at flux control of water measurement system have non-linear variety as well as indetermination, the good controlling effect cannot be gotten if normal PID method is employed.Fuzzy PID parameters adaptive controller and based on PLC are designed, According to deviation and deviation variety rates come to adjustment parameter, In addition, the advanced GSM set net technique is adopted, Satisfying the system data delivers real time, high-speed and high and reliability request, And satisfy the water measurement quantity and of sluice that opens one degree information collections to deliver.
