In this paper, a detailed study on the local real time control of moveable sharp-crested weirs in sewer channels is presented. Firstly, an experimental analysis aimed at determining the hydraulic behaviour of the regulator under both free flow and submerged flow conditions was carried out. Then, a numerical investigation into the calibration of proportional (P) controllers for the weir control was performed. In particular, suitable values were evaluated for the controller proportional parameter in order to obtain quick regulations and avoid the occurrence of permanent water level oscillations behind the weir. A dimensionless approach was adopted for the generalisation of the results.
本文对下水道渠道中可移动锐缘堰的局部实时控制进行了详细研究。首先，进行了旨在确定调节器在自由流和淹没流条件下的水力特性的实验分析。然后，对堰控制的比例（P）控制器的校准进行了数值研究。特别是，评估了控制器比例参数的合适值，以实现快速调节并避免堰后出现永久性水位振荡。采用无量纲方法对结果进行了归纳。
