Moveable gates for the real-time control (RTC) of sewer systems storage capacities are usually operated by controllers which, on the basis of local water level or flow velocity measurements, calculate the regulation errors of the monitored variables, determining the necessary regulator movements to lead the flow conditions to the desired set point. In this paper the results of an investigation on the influence of proportional-integral-derivative (PID) controllers and programmable logic controllers (PLC) for the RTC of moveable sluice gates positioned into sewer systems are presented. The analysis of response time, damping and regulation errors provided information on the PID parameter calibration values and on the PLC control function performances. A comparison between the two kind of controllers has also been carried out.
用于下水道系统存储容量实时控制(RTC)的可移动闸门通常由控制器操作,这些控制器根据当地水位或流速测量值,计算监测变量的调节误差,确定必要的调节器动作,以使水流条件达到所需设定点。本文介绍了对用于下水道系统中可移动闸门实时控制的比例积分微分(PID)控制器和可编程逻辑控制器(PLC)影响的调查结果。对响应时间、阻尼和调节误差的分析提供了有关PID参数校准值和PLC控制功能性能的信息。还对这两种控制器进行了比较。
