DEVICE FOR CONTROLLING DRIVES OF ANTENNA STATION OF RADAR STATION Russian patent published in 2016 - IPC G05B11/00 

FIELD: machine building.

SUBSTANCE: invention relates to universal automated systems for controlling drives, mainly drive of azimuthal antenna rotation with support platform stabilisation of antenna post of ship radar station. Drive control device, comprising a channel of generating of readings of angular position sensor of slowly rotating antenna (MVA), which includes series-connected error detection unit, unit of proportional-integral-differential (PID) controller and unit for generating engine control output signals, additionally includes a generator of frequency grid, a unit of initial plants, to first and second outputs of which are respectively connected input of generator of frequency grid and input of an approximation unit of angular position of fast rotating antenna (BVA), output of which is connected to first control unit input and input-output, second input is connected to output of automatic selection of a navigation channel, and output signal of preset angular position of antenna is connected to second input of error detection unit, furthermore, channel for generation of readings of angular position sensor MVA comprises angle sensor excitation unit and series-connected input circuit unit, phase-amplitude conversion unit and amplitude-code conversion unit, output of which is connected to first input of error detection unit, input circuit unit is configured for analogue-to-digital conversion of both voltage and current signals depending on type of antenna of angular position sensor connected to input of input circuits, and phase-amplitude conversion unit is configured for both phase conversion of output signals of input circuits and direct transmission to inputs of amplitude-code converter inputs of initial setting unit input circuits, and amplitude-phase conversion unit are connected to third output of initial settings, first output of generator of frequency grid are connected to clock inputs of excitation and angle sensor of input circuit unit, to second output is connected clock input of amplitude-code converter, to third and fourth outputs are connected corresponding clock inputs of an approximation unit of BVA angular position, and to fifth output - clock input of automatic selection of navigation channel, output of amplitude - code conversion unit, where a code of current angular position of MVA, is also connected to third control unit input and input-output, fourth input-output of which is intended for connection of communication channel with a control panel of radar station.

EFFECT: higher reliability, accuracy of adjustment of rotation speed and stopping antenna in specified angle to ensure stabilisation of support platform for roll and trim.
