Abstract :
By researching the stability analysis methods of the complicated nonlinear time-variant system, some new analysis approaches are presented in this paper, which include the parameters fixing in Simulink and the system containing nonlinear links linearization in Matlab. In addition, the feasibility of using the analysis method of nonlinear time-variant system and the decoupling method for anti-aero missile control system with channel couple are discussed. The simulation results show that the stability analysis for a missile is provided in Simulink, which satisfy the requirement of analysis of anti-aero missile control performance.
