Design of Missile Blended Control System Based on Fuzzy Logic

建立了具有气动力/直接侧向力混合控制的导弹动力学模型,设计了常规气动力控制和模糊逻辑侧向力控制的导弹复合控制系统.根据控制系统跟踪性能要求和直接力控制原则,采用进化策略对常规气动力控制器参数和模糊直接力控制规则进行优化设计.仿真结果表明,导弹复合控制系统具有良好的快速大机动跟踪能力,可实现导弹气动力和直接侧向力之间合理的控制分配.

The blended dynamic model of missile with aerodynamic fin and side thruster is developed. The blended missile control system integrated traditional controller using aerodynamic fin with fuzzy logic controller using side thruster is designed. The parameters are optimized with respect to the tracking performances of missile control system and the criterions of side thruster control based on evolutionary strategies. The simulation results show that the missile control system with side thruster tracks the great maneuver acceleration command accurately and rapidly and the reduced aerodynamic control effectiveness is compensated by the side thruster. The control allocation between the aerodynamic fin and side thruster can be implemented intelligently and correctly.
