Effective control of a hybrid system of generation and distribution of electricity when moving autonomous uninhabited underwater vehicle

For the movement of an autonomous underwater vehicle (AUV) at a speed from a wide range due to the increased density of the marine environment, various actuators are used, which differ not only in the principle of operation, but also in the current consumption that varies over time. Because of this, power sources that are different in principle of action are needed. In this regard, the movement control of AUVs necessitates solving the problem of effective control of the energy generation and distribution system, which is understood as determining the necessary composition and parameters of power sources, as well as the distribution of consumers on buses under strict time limits. The purpose of the work is the development of effective control of the AUV energy generation and distribution system to ensure its movement with specified parameters. The analysis of connecting/disconnecting consumers revealed that all situations can be reduced to two types of control: the first — in which it is not known in advance which of the consumers will be connected and what current it will consume; the second — in which the composition of consumers and the amount of current consumed by them are known. To determine the management of consumer switching, the task is formalized as the task of packing in containers, for the solution of which heuristic algorithms exist. An analysis of existing algorithms in relation to the problem to be solved allowed us to determine that the Best Fit and Best Fit Decreasing algorithms provide effective control of the power generation and distribution system. An example of controlling a hybrid system for generating and distributing electricity when changing the parameters of the movement of the apparatus is given.
