(.): The paper is devoted to the development and study of an intelligent system of adaptive automatic control with a given target based on the use of artificial neural network of forward propagation. The control object is an autonomous unmanned underwater vehicle (AUV). In this paper, it is proposed to feed the signals received from the systems of the AUV to the input of the neural network, and use the output signal of the neural network for control to keep the vehicle on a given trajectory. As a result of this work, a model and a learning method are proposed that lead to holding the ANPA on a given trajectory under an external influence with a natural constraint for the considered mobile robot. Given a continuous preset trajectory and discrete signals from the ANPA systems, this allows following the preset trajectory with a simple intelligent control system that does not require large computational power. The proposed method of control system training allows pre-training on a numerical model of vehicle motion with random external influences, but does not require such pre-training under certain conditions. It is shown, in particular, that in the case of a sufficiently large learning rate, the model has time to rearrange itself and reacts to changed circumstances. The proposed intelligent system of adaptive automatic control can find application in those cases when the characteristic time of changes in the system is of the order of the training time, and the trajectory of motion satisfies the requirements stated in the paper.
