Annotation: This paper presents the features of the designing control systems for high-precision electric drives of the power gyroscopic devices – reaction wheels and control moment gyroscopes. The accuracy and dynamic performance are improved by applying the principle of phase synchronization, etalon digital model in the control loop and the use of high-performance digital computing systems. The block diagram, its description and experimental results are presented in the paper.

Keywords: reaction wheel, control moment gyroscope, dynamic torque, etalon digital model, frequency-phase discriminator, permanent мagnet synchronous motor, orientation and stabilization system of the spacecraft
