METHOD OF DIGITAL FILTRATION OF NOISE COMPONENT IN INERTIAL SENSORS Russian patent published in 2018 - IPC G01P3/00 

FIELD: instrument engineering.

SUBSTANCE: invention relates to the field of instrumentation and can be used in the construction of uniaxial and triaxial meters of angular velocities and linear accelerations with digital information output. Stated task can be solved by the proposed method of digital filtering of the noise component of the output signal in inertial sensors, in which the digital filtering of the noise component of the output signal of the inertial sensor is carried out by separating from the sensor output signal for a given time interval its average value, determining in a subsequent time interval the sign of the noise component relative to the average value of the output signal determined in the previous time interval, and subtracting the noise component of the given value from the output signal, taking into account its sign.

EFFECT: object of the invention is the possibility to provide a predetermined level of digital filtering of the noise component in the output signal of the sensor with a minimum phase delay, which is in some cases a decisive argument for the possibility of using sensors in complex control systems for aircraft.
