Research on Attitude Law of Mass Moment Missile

An attitude control law based on fuzzy logic is presented for the mass moment missile in intra-atmospheric space. After constructing the model of the attitudinal movement with three -axial stabilization, the fuzzy rule tables corresponding to the moving mass position in respective axial are constituted. According to analysis of the relation between angular acceleration and searching condition, three moving mass positions are regulated in phase. Simultaneously the proportional differential (PD) parameters are offline revised using genetic algorithm according to the specific performance index. Simulation results show that the system stabilization can be satisfied to realize efficiently attitude adjustment for missile
