An ESG-based Sensor for Measuring Three Angles of a Moving Object Rotation: Some Issues of the Theory and Mathematical Simulation of its Operation

详细

The main features of the design and circuitry of an ESG-based sensor for measuring three angles of a moving object rotation are discussed. The physical basis of the proposed engineering solution is generation of rotational and single- or two-component translational motion of an electrostatically suspended rotor with the use of a torquer and force transducer. The theoretical justification, algorithms and the results of comparative mathematical simulation are given. It is shown that in the case of single-component rotor oscillations in the equatorial plane, the error in determining the azimuth angle is three times smaller than that in the case of two-component oscillations.
