ANALYSIS OF VECTOR’S ERRORS OF MANAGEMENT BY A SHIP
Abstract
Factors, conducing to appearance of vector’s errors of turn of ship, which the error of change of position of feather of helm and error of moment of time of beginning of maneuver of turn are, are exposed. The mechanism of forming of vector’s errors of turn is shown and the formulas of estimation of values of vector’s error of turn of ship at appearance of error of change of position of feather of helm and error of moment of time of beginning of maneuver of turn are got.
Procedure of determination of size of vector’s error of turn of ship is offered, arising up from the error of change of position of feather taxiing and depending on the chosen dynamic model of rotatory motion of ship. Analytical expressions for estimation of size of vector’s error for the dynamic model of rotatory motion of ship of the third order, which most adequate to the real process of turn of ship, are got.
Supposition about the law of distributing of constituents of vector’s error of turn is done, which the mixed laws of probability distribution of the first and second types are offered as.
