Abstract: This paper proposes an approach of integrated analysis of performance and reliability for missile's flight control system under the effects of some important factors. The disturbance models of wind, structural errors (including missile mass asymmetry, body un-coaxial, airfoil installation angle error and rudder null position), thrust deviation and hardware failure are established. The method of reliability simulation, approach of implementation, detailed algorithm process and formulas of computing reliability are given. A ×-missile's flight control system is taken as example, and the effects of these factors on the missile's reliability are analyzed by plenty of simulations. The disturbance models and integrated analysis of reliability are proved right by the simulation tests.
