Description

technical field [0001] The invention relates to the field of real-time control of urban drainage systems, in particular to a mixed model of simulation control of urban drainage systems based on a mechanism model, a conceptual model and a data model of Matlab. Background technique [0002] With rapid urbanization and increased frequency and magnitude of extreme rainfall events due to climate change, urban drainage systems are being stressed, increasing the risk of waterlogging and combined sewer network overflow. Real-time control of urban drainage system is a reliable means to improve the performance of drainage system. Real-time control is based on the important process variable data of online monitoring, uses the online model to dynamically adjust the control strategy, and performs real-time intervention on the operation of drainage facilities and sewage treatment plants through control equipment. [0003] In the simulation of urban drainage system, the online mechanism m...
