ANTIFAILURE PROTECTION OF ROCKET MULTIPLEX CONTROL SYSTEM Russian patent published in 2014 - IPC B64G1/24 

Abstract RU 2521117 C1

FIELD: engines and pumps.

SUBSTANCE: proposed method comprises generation of data signal in every channel corresponding to a definite combustion chamber as the difference between command signal and feedback signal, generation of control system channel cut-off signal as the signal of setting actuator rod on said channel to mid position. Channel cut-off signal is generated in case the data signal modulus integral calculated at preset-duration time interval exceeds the preset threshold. Note here that command signals of other channels are generated as sums of or difference in pitch, yaw and bank control signals and cut-off channel feedback signal with coefficients depending on cut-off channel number so that required summed pitch, yaw and bank control moments are actuated.

EFFECT: higher reliability at fault of control system channel.
