AUTOPILOT SYSTEM Russian patent published in 2010 - IPC G05D1/00 

FIELD: physics.

SUBSTANCE: autopilot system has a two-channel circuit for processing the input signal of the autopilot system and identical 1^st and 2^nd channels respectively having 1^st and 2^nd phase detectors, 1^st and 2^nd low-pass filters, 1^st and 2^nd adders, 1^st and 2^nd modulators and a 3^rd adder. The output of the 1^st modulator is connected to the first input of the 3^rd adder and the output of the 2^nd modulator is connected to the second input of the 3^rd adder whose output is the output of the autopilot system. The autopilot also has 3^rd and 4^th phase detectors whose data inputs are connected and form the second data input of the autopilot system. There also 1^st, 2^nd, 3^rd and 4^th circuits for selecting the period average carrier input signal, 3^rd and 4^th low-pass filters, 1^st and 2^nd functional units and 1^st and 2^nd limiters. The gain control channel consists of series-connected adder, square-rooting circuit and non-linearity unit.

EFFECT: accuracy of generated autopilot control signal for a spin rocket with single-channel control with variation of its rotation frequency.
