水闸群耦合式MPC控制模式与算法研究
Using model predictive control algorithm to improve gate group control in large-and long-distance water transfer project
摘要
Abstract
[Objective]Large-scale,long-distance water transfer projects are critical for balancing spatial water resource distribution,but their gate group control faces lags in water transfer time,poor synergy and'dimensional disasters'in centralized control,which hinder control efficiency and precision.Distributed control can alleviate these limitations but could lead to subsystem coupling and decoupling losses.We proposed a method in this paper to optimize the gate group control using the model predictive control(MPC),to improve water resource control accuracy and use efficiency in automation and intelligent construction of engineering projects.[Method]Three MPC-based gate group control model were designed:centralized model predictive control(CMPC),distributed model predictive control(DMPC),and coupled distributed-centralized model predictive control(D-CMPC).Their performance was tested and compared against the 36#-41#Gate Section in the South-to-North Water Diversion Middle Line Project under nine different combinations of targeted water level changes and water diversion disturbances.The analysis focused on the effects of the control on gate-section water levels and over-gate flow.[Result]For targeted water level control,D-CMPC outperformed CMPC and DMPC,and its regulation efficiency improved by 19%-71%,and cumulative water level fluctuations decreased by 14%to 79%.In respondence to water diversion disturbances,D-CMPC was also the best in keeping water level stability.[Conclusion]The coupled MPC-based gate group control strategy(D-CMPC)effectively resolves the key challenges in large-scale water transfer project control,providing a robust technical support for helping design automation and intelligent upgrading of hydraulic engineering projects.关键词
