METHOD FOR FORMATION OF CONTROL COMMANDS OF ROLLING TWO-CHANNEL MISSILE Russian patent published in 2006 - IPC F41G7/20 

FIELD: development of telecontrol systems of rolling missiles, applicable in complexes of tank and antitank weapon, as well as in small-sized antiaircraft systems.

SUBSTANCE: in the known method for formation of control commands of rolling two-channel missile including formation of control signals U₁,U₂ of the first and second channels proportional to the linear deflections of the missile relative to the aiming line in the horizontal and vertical planes, formation of periodic signals of carrier frequency s(γ),c(γ) proportional to the sine and cosine of missile bank angle γ, formation of control signals U_p1,U_p2 by the first and second control actuators by amplitude modulation of the carrier frequency and subsequent summation of them, simultaneously with formation of the control signals of the first and second channels signals U_δ1,U_δ2 are formed that are proportional to the deflection angles of the first and second control actuators, they are subjected to demodulation by multiplication by the carrier-frequency signals and subsequent amplification, then they are subtracted from the control signals of the first and second channels in compliance with the first preset mathematical dependences, amplitude modulation of the carrier-frequency signals is realized by the obtained signals of the difference in the first and second control channels, and summation is performed in compliance with the second mathematical dependences.

EFFECT: enhanced accuracy of missile guidance to the target due to elimination of the phase coupling of the missile control channels caused by the sluggishness of the control actuator and by the spread of the missile rolling speed by correction of the phase of the control actuator input signals in accordance with the current phase lag of the output signals.
