This paper describes research results of influence of voltage variations in the hysteresic gyroscopic motor (augmenting, nominal, magnetic biasing impulse) on the angular error of a monoaxial gyrostabilizer. The considered model of the monoaxial gyrostabilizer takes into account destabilizing effect produced by the hysteresic motor and associated with variations of the motor power supply parameters on the angular error. The research was carried out on the basis of full-scale tests in accordance with the planned full-scale experiment for the purpose of obtaining functional dependence of independent from the flywheel motor power supply parameters component of gyro unit deviation speed on power of the gyroscopic motor, with the subsequent transition to mathematical model of a monoaxial gyrostabilizer.
