EFFECT OF YAW AND DRIFT OF A SHIP ON THE OPTIMAL DYNAMIC CHARACTERISTICS OF THE GYRO-VERTICAL WITH INDIRECT CORRECTION

This article contains an analysis of the optimal dynamic characteristics of a gyro-vertical with indirect electromagnetic correction installed on a ship undergoing oscillations with respect to the yawing angle. The condition of minimum error dispersion is used as the optimalness criterion. The effect of the variable drift angle of the ship and cross coupling between the correction channels on the behavior of the gyro-vertical in the steady state is investigated under defined assumptions. It is noted that in the present paper it is assumed that the yaw of the ship occurs only from inaccuracy of the automatic steering, neglecting the effect of other factors. The results of the investigation indicate that under the defined assumptions it is possible not to consider the variable drift angle of the ship in the equations of motion of the gyro-vertical and to consider the gyro-vertical channels independent. Thus, the magnitude of the yawing angle of the ship only affects the behavior of the channel with respect to one of the two angles between the coordinate systems representing the error of the gyro-vertical.
