FIELD: physics. ^ SUBSTANCE: data on the current change in wind velocity öV=V0-Vl are generated in a comparator unit based on wind velocity data in successive time intervals öt obtained from a wind-wave disturbance sensor and from wind velocity measurement results V0 at the beginning of each time interval and Vl during its end in each i-th interval. further, acceleration i=öV/öt is calculated and stored, which is compared with a new value i+l in the (i+l)-th interval. Comparison results >0 or <0 are henceforth summed up with subsequent comparison results such that they compensate for each other during their random alternation. If a positive value of repeats at least 2n-1 times with possible occurrence of =0, the time interval öt is shortened times, which indicates occurrence of squall wind. On that basis, control signals are generated taking into account deviation of coordinates. For groups of n positive values of following this event, the coefficient is stored without changes, but control signals are corrected each time taking into account deviation of coordinates. If a negative value of repeats at least 2n-1 times successively with possible occurrence of =0, =1. For recurrent groups of n negative values of , the coefficient is stored without changes, which indicates the end of the squall. If =0 on any time interval öti, control signals are stored in a format adopted in time interval öti-l. ^ EFFECT: invention provides generation of control signals in advance using the actuation mechanism of a ship during its dynamic positioning in conditions for occurrence of a squall. |
