Determination of the Torque Motor Parameters of the Indicator Gyrostabilizer Using the Vyshnegradsky Criterion

This paper presents the possibility of using the Vyshnegradsky diagram to study the influence of DC torque motor parameters on the synthesis of the feedback loop of the indicator gyrostabilizer. The filtering properties of a DC torque motor are determined by its electromagnetic time constant. These properties allow to use motor's transfer function to limit the frequency range of the differential link of the controller. The requirements for the performance of the stabilization motor are determined. The implementation of current feedback in the torque motor to make modifications in its electromagnetic time constant is considered. Its influence on the cutoff frequency and the quality of regulation of the gyrostabilizer is investigated.
