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 ?of the control in plane s or a pole atin plane z, with that, T is a sampling period of a discrete input signal of the proportional-integral control, and ?>0. Circular frequency ?of the control is chosen equal to resonant circular frequency ?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.18 cl, 21 dwg |
