Technology of cybernetic models’ creating for the synthesis and refinement of autonomous underwater vehicle motion control system controllers

The technology of cybernetic models’ creating for the synthesis and refinement of algorithms for controlling the autonomous underwater vehicle’s (AUV’s) motion is considered. The paper gives a description of the following sequence of actions performed at each stage of the cybernetic model development: dynamic model type and parameters identification, controller type selection, construction and analysis of the considered control loop block diagram, determination of the controller’s optimal parameters. The synthesis of heading, pitch and depth stabilization regulators for streamlined shape AUV during propulsion engines controlling is performed. The results of numerical modeling and research of the various factors influence on the quality of control are presented.
