MATHEMATICAL MODELING OF HYDRODYNAMIC PROCESSES IN NAVIGATION PASSES AND THE OPTIMAL CONTROL OF VESSEL'S PASSING THROUGH A SHIPPING LOCK

摘要

The paper takes some authors experience into account in investigation of unsteadyrnhydrodynamic processes that occur in navigation structures. Mathematicalrnformulation of this problem is based on the coupled system of equations of the longrnwaves theory and those of vessel displacement in water into a lock chamber andrncanals.rnOptimization problems on reduction if operational time or energy consumption underrnthe limitations caused by technical characteristics and conditions are underrnconsiderations with the same purpose it is proposed to introduce the additionalrnfacilities as well as an active control element. It is supposed that the use of suchrnadditional active control devices enables to increase the technical efficiency ofrnnavigation structures.
