CONTROL MODULE AND DEVICE FOR RETURN TO INITIAL STATE OF OSCILLATOR EXCITED BY HARMONIC OSCILLATION, AS WELL AS SENSOR OF INSTANTANEOUS ANGULAR SPEED Russian patent published in 2015 - IPC G05B5/01 

FIELD: measurement equipment.

SUBSTANCE: invention relates to a control module for return to initial state of deviation of an oscillator, to a device including such control module and to an operating and manufacturing method of such sensor. Technical result consists in improvement of characteristics of a control during the transient period caused by an exciting value of deviation of the oscillator. The control module includes a proportional-integral control for predetermined harmonic values. A transfer function of the proportional-integral control for the predetermined harmonic values has a complex-conjugate pole at circular frequency ω_r of the control in plane s or a pole at $$e^{\pm j{\omega }_{r}T}$$ in plane z, with that, T is a sampling period of a discrete input signal of the proportional-integral control, and ω_r>0. Circular frequency ω_r of the control is chosen equal to resonant circular frequency ω₀ of the oscillator. Parameters of the control are determined for example by compensation of poles and zero points.

EFFECT: control module provides for a possibility of wide-band control of harmonic oscillators in instantaneous angular speed sensors.
