THE METHODOLOGY FOR DECREASING THE MEASUREMENT ERROR OF THE MEAN ANGULAR ROTATION VELOCITY OF CONTROL MOMENT GYROSCOPE GYROMOTOR SUSPENSION

The assessment of angular rotation velocity of control moment gyroscope gyromotor suspension is a challenging technical task made even more complicated by the necessity to carry out a significant number of process checks at different lifecycle stages. To develop a methodology for decreasing the measurement error of the angular rotation velocity of control moment gyroscope gyromotor suspension that would enable the engineers to take into account the effect of systematic harmonics of angle sensor error. The dependency of the measurement error of the mean angular rotation velocity of gyromotor suspension on its actual rotation velocity and initial angular position was established. This article presents an assessment of the measurement error of the mean angular rotation velocity based on the data received from the angular position sensor of an actual control moment gyroscope. A methodology is offered for decreasing the measurement error of the mean angular rotation velocity of gyromotor suspension by selecting a set of optimal initial angular position and specified angular rotation velocity parameters. The results received in the course of the research can be applied to decrease the measurement error of the angular rotation velocity of control moment gyroscope gyromotor suspension at different lifecycle stages. The presented methodology can be applied to assess the measurement error of the mean angular rotation velocity of any electric drive that includes an angular sensor for which it is possible to divide its angular position measurement error into systematic harmonics.
