title = "Dynamics Modeling and Attitude Control for a Telescope Satellite with Large Inertia",
abstract = "The dynamics of a 70m large-size and large-inertia flexible telescope satellite is analyzed in this paper and establishes its dynamics equations under unconstrained mode. Considering the large inertia of flexible attachment, the consistent mass matrix is used to describe its mass characteristic, which is different from traditional flexible satellites. The calculation method of the translational and rotational coupling coefficients is given. We expand the mode coordinates and solve the generalized characteristic equation to obtain the unconstrained modal frequency. The result is similar to the ANSYS software. The stable attitude control simulation is carried out using the adaptive sliding mode controller, which illustrates the coupling characteristics of the large-size flexible structure and verifies the dynamics model.",
