- Abstract:
- Modeling technology of urban drainage system (UDS) is an important means to comprehensively reflect the operation state of UDS. With the development of intelligent control technology of UDS, the on-line application of drainage system model has been paid more attention. In the drainage system model, pipeline simulation occupies the core position, and the reliability and timeliness of its simulation directly affect the overall performance of the model. In order to overcome the modeling problems caused by complicated parameters and slow running speed, high complexity and difficulty in applying to the optimal regulation of the controller in the classical mechanism model, several efficient data-based modeling techniques, such as moving average algorithm, linear fitting method and transfer function method, are introduced, and their feasibility and reliability are described from the perspective of realizing the on-line and efficient real-time application of the model. Finally, their simulation performance comparison under the changing conditions of pipe network is given with practical cases.
