METHOD TO GENERATE CONTROL SIGNAL IN TRACKING SYSTEM Russian patent published in 2012 - IPC G01S7/00 

FIELD: instrument making.

SUBSTANCE: in the method to generate a control signal in a tracking system based on serial cyclic measurement of a displacement angle (DA) between a direction to an object and a sighting line of a controlled device, and correction of an error signal on the basis of forecast with account of a delay in a control circuit, the specified control signals on the first and second measurement cycles are generated based on the current DA measurement; from the second cycle of measurement the DA is forecasted for the time of measurement cycle by versions of hypotheses for forecasting: curves of the first and second order using, when measuring their coefficients, from 2 to N last measured and memorised DA (N≤N_max); from the third cycle on the current cycle of measurements from versions of hypotheses, for which forecasting was made at the previous cycle, the one is selected, which provides for minimum error between the hypothesis forecasting and current measurement of DA; for a curve of an appropriate order by appropriate quantity of used DA measurements, including the current one, curve coefficients are determined for extrapolation of an error signal; it is extrapolated in accordance with it for the time of delay in a control circuit, and the corrected DA value is sent to generate a control signal.

EFFECT: higher accuracy of tracking over an object under a wide range of input error signal speed variation.
