control and adjustment systems for antenna drives. SUBSTANCE: system that may be used for digital control of metrological radar antenna drive, for automatic feedback control and for positioning servo systems has microprocessor, stepping motor, motor power control unit, harmonic gear transmission, antenna shaft angular position sensor, and angle-to-code converter; angle control command signal is system input connected to signal input of microprocessor whose data inputs are connected to outputs of angle-to-code converter; error output of microprocessor is connected through motor power control unit to stepping motor control winding and output of microprocessor control bus, to control input of angle-to-code converter; stepping motor output is connected to harmonic gear transmission unit which is system output for coupling with antenna shaft also connected with input of synchro resolver whose output windings are connected to input of angle-to-code converter. EFFECT: enhanced precision. 1 dwg |
