MISSILE CONTROL SYSTEM Russian patent published in 2003 - IPC

FIELD: defense equipment, in particular, means of fighting against small-sized targets, applicable in the missile control systems forming on board the motion control commands. SUBSTANCE: the system has an equipment for formation of commands of missile guidance on the target located on the control points, and on the missile it has series-connected receiver and equipment for separation of channels and decoding, whose pitch and heading outputs are connected to the first and second inputs of the command converter via the first and second multiplier units respectively, as well as a control surface channel that includes an adder, feedback potentiometer and a control winding of the steering gear kinematically connected to the wiper of the feedback potentiometer. The first input of the adder is connected to the output of the command converter, the second inputs of both multiplier units and the first output of the feedback potentiometer are interconnected and connected to the power source. The missile control system and the control surface channel uses two switch-controlled power amplifiers, the second control winding of the steering gear, correcting filter, Schmitt trigger, inverter and the second power source, whose characteristics are identical to the first power source. It has enhanced the accuracy of the control system due to the fact that the instability of the missile transmission factor at variation of the value of voltage of the power source is completely eliminated, which makes it possible to feed the missile equipment from an unstabilized power source, in this case there is no control error caused by a drift of the level of direct voltage in the autopilot. EFFECT: enhanced accuracy of control. 2 cl, 2 dwg
