Study on the theory and simplified equations of mass moment control missile

In order to research the dynamic of moving mass actuation missile, the dynamics models are presented for mass moment control missile in the paper. Theoretic analysis, simulation of the main operation ingredients of effecting reaction time is discussed under different condition. Moving mass actuation technique offers significant capability to change missile attitude. Via perturbation method of the modal parameters, the simplified equations are presented on condition that the spin is slow. Simulation results indicate that the models are the basis for the nonlinear control design and analysis.
