摘要

FIELD: method and systems of control of flight vehicles, in particular spin-stabilized missile forming the control commands on-board, for example, in the beam TV-guidance system.;SUBSTANCE: the moment of appearance of the spinning signal is preset on the missile from the moment of fixing, in addition from the moment of fixing a time interval is preset during which a double-sideband linearized signal is formed, and on termination of this interval up to the end of the flight- a single-sideband one, the linearized signals re compared with the decoded received signals of control in heading and pitch with regard to missile spinning, as a result, control commands are produced. The missile uses series-connected reversible linearizer and relay element. The second input of the relay element is connected to the output of the co-ordinate converter, and the output of the relay element is connected to the input of the control actuator, the output of the fixing device is connected top the input of the functional mode of the reversible linearizer. The first and second control inputs of the reversible linearizer are connected respectively to the first and second outputs of the roll-angle pick-off, which made it possible to enhance the reliability of functioning. Proposed is also the method of forming of the double-sideband linearized signal at which the pulse signal is produced in the form of a train of bank pulses with zero and unity logical levels. The durations of the bank pulses are measured, and the value of swing of the front of the rise or sag of the linearized signal during the running of the subsequent bank pulse is set according to the duration of the previous pulse, the front of the rise and sag is set by the respective logical level of the bank pulses. The reversible linearizer uses a control unit and a series-connected "exclusive OR" circuit, "duration-to-code" converter and a computer, whose output is connected to the signal input of the integrator. The second input of the computer is connected to the first output of the control unit, the second output of the control unit is connected to the control input of the integrator. The output of the "exclusive OR" circuit is connected to the first input of the control unit, whose second input is connected to the output of the fixing device, the integrator clock input is connected to the second output of the "duration-to-code" converter.;EFFECT: enhanced reliability at an enhanced accuracy of forming of control commands.;4 cl, 6 dwg
