AI Technical Summary
Existing lock control systems are unable to predict and suppress local water level fluctuations in advance. Fixed scheduling steps lead to high computational loads and ineffective mechanical wear. Pure data-driven models lack physical boundary constraints, posing safety risks.
A deep learning-based approach is adopted to predict water level and flow velocity through a physical information long short-term memory network, calculate the momentum equation residual by combining shallow water equations, dynamically calculate the upper and lower limits of valve action rate, and use a policy neural network to generate control commands within the dynamic safety boundary and dynamically adjust the scheduling step size.
When a turbulent flow trend is predicted, the system automatically suppresses large fluctuations in water level, improves the safety and water surface stability of the lock filling and emptying process, reduces the computational load and mechanical wear of the controller, and enhances the engineering reliability of the control system.
