METHOD FOR STABILIZING MOVEMENT OF AIRCRAFT WITH A STRUCTURALLY UNSTABLE OSCILLATOR Russian patent published in 2018 - IPC G05B13/02 G05B11/01 

FIELD: aviation; control systems.

SUBSTANCE: invention relates to the field of designing control systems for aircrafts (AC), and can be used by the control system in the device of the proportional-integral-differentiating regulator of the automaton of the stabilization of motion to ensure the stability of the oscillations of the liquid filler in the fuel tanks. Parallel control loop is constructed using a high-Q resonance filter at the frequency of a structurally unstable oscillator. Harmonic signal, in-phase with the oscillations of a structurally unstable oscillator, is isolated, which, by connecting it to the output of the automatic stabilization of AC, ensures phase stabilization of structurally unstable oscillations of the liquid filler in the fuel tank of the AC.

EFFECT: stability factor and quality of movement of AC with liquid fuel in tanks are increased by the means of the control system, the reliability of the control system increases, the probability of an emergency situation of the control system decreases.
