| Summary: | In this paper, the study of nutation damper using
magnetic hysteresis is presented. There are various types of
nutation damper existed and are discussed in many papers
including an active nutation damper and passive nutation damper.
This paper focuses only the usage of passive nutation damper
because of the size limitation of microsatellite body that constraint
the benefit of using active nutation control. Attitude motion of the
microsatellite is described by using kinematic Euler equation
where the approach of differential equation was used. The
interaction of magnetic hysteresis with earth magnetic field is
studied in this paper. Derivation of the governing equation in
determining the attitude is briefly discussed. The effects of
changing the parameter of damper characteristics as well as the
effect of changing the model of the microsatellites; cylindrical
and cube shape is considered. The attitude dynamics are observed
by simulating the equations using MATLAB software and the
results from simulation are discussed and concluded. |
