Research is done for simplified dynamics equations and control system design of the mass moment control missile in this paper. The paper begins with a detailed description of the proposed control architecture and the inversion errors counteraction by taking advantage of the functional capabilities of the radial basis function neural networks (RBFNN), which is demonstrated by Lyapunov stability theory.After, the equation and approximate inversion of the missile's six-degree-of freedom nonlinear dynamics are presented,the control systems are then designed.It is shown by the simulations that the method provided in the paper has the excellent ability to reconstruct the inversion errors.
