METHOD FOR CONTROL OF ROCKET WITH AERODYNAMIC CONTROL SURFACES Russian patent published in 2002 - IPC

FIELD: control systems of roll-stabilized rockets, whose airframe is made according to the aerodynamic canard configuration. SUBSTANCE: the method consists in forming of control commands in the form of three- position pulse-width modulated signals, supply of them to the rocket control actuator and deflection of the aerodynamic control surfaces by an angle maximum in modulus and coinciding with the control command in sign at non-zero positions of the control command and by an angle whose direction and value are determined by the relative position of the velocity vector and longitudinal axis of the rocket, - at a zero position of the control command forming of control commands in the form of three-position pulse-width modulated signals is accomplished at a doubled rolling speed of the rocket in two mutually perpendicular planes in accordance with definite mathematical dependences. EFFECT: enhanced maneuverability and reduced required speed of response of the control actuator at a control of rockets that are low-stable and non-stable in flight and have rolling aerodynamic control surfaces. 5 dwg
