CONTROL OF THE WATER LEVELING PROCESS BETWEEN THE SHIPPING LOCK CHAMBER WITH WATER DISTRIBUTION AND THE POOL

Abstract

The development of solutions to increase the throughput capacity of inland waterways through the effective management of the water supply system of the shipping lock chamber corresponds to the priorities of the development of inland water transport of the Russian Federation. The subject of research is the process of leveling the water levels in two communicating vessels. At the present stage of researches development, the solution of this problem is associated with an iterative procedure, the convergence of which essentially depends on the choice of the initial approximation and the step of numerical integration. The method of synthesis of the optimal control of changing the water level in the lock chamber is proposed in the paper (knowledge of an object as a single whole, in the unity and interconnection of its parts). At the same time, the solution of the problem of combined optimal control of a nonlinear system according to the hierarchy of functionals is considered. An idea of a self-organizing optimal controller with Krasovsky extrapolation is given. Particular attention is paid to control optimization at low computational costs in the process of system formation. The use of predictive models proposed in the paper makes it possible to obtain practical algorithms that do not require deep fundamental knowledge of control theory when they are introduced. The efficiency of the studied algorithms, when the process time changes, is shown. The presented solution makes it possible to carry out a comparative analysis of various methods of leveling water levels between the chamber of a shipping lock with a distribution power supply system and the corresponding pool, which allows solving one of the urgent problem of increasing the throughput of shipping locks in a section of the waterway with the unconditional fulfillment of ensuring safe locking conditions.
