Abstract: Accurate dynamics characteristics are important for rotary inertia identification. Considering the effect of solar cell array rotation in dynamics, a method of inertia identification is proposed, which is applied to identify the body inertia and solar cell array inertia simultaneously. Thinking of the coupling between the variables, the optimized identification model with constraint is deduced based on the modeled multibody attitude dynamics. The precise solution is achieved via the algorithm of constraint least squares. Finally, the feasibility of the identification method is verified by simulation and calculation.

Key words: multibody attitude dynamics, rotary inertia identification, constraint least squares
