METHOD OF FAULT-TOLERANT AUTOMATIC CONTROL OF NAVIGATION Russian patent published in 2011 - IPC B63H25/04 

FIELD: transport.

SUBSTANCE: invention relates to ship building. Proposed method exploits diagnostics unit and the following modules, i.e. program, computer, actuators, measuring and standby modules: computer - δ_pr.stand., actuators - δ_stand. measuring - φ_stand., and model of actuators - δ_mod. Diagnostics unit generates: First signal of course angle difference signal (from measuring module) and preset course angle (from program module) |φ-φ_pr.|, second signal of course angle difference (from measuring module) and signal of standby course angle (from standby measuring module) |φ-φ_stand.|, third signal of differential signals δ_pr. (from computer) and signal δ_pr.stand. (from standby measuring module) |δ_pr.-δ_{pr stand.}|, fourth signal of signal difference δ (from module of actuators) and signal δ_mod. (from standby module of model of actuators) |δ-δ_mod.|. Difference signals are compared with tolerances. Results of said comparison allow automatic reconfiguration of automatic navigation control system architecture.

EFFECT: automatic control at failure in one of automatic navigation control system modules.
