摘　　要：针对姿控式直接力/气动力复合控制导弹喷流干扰较大的特点,基于自适应遗传算法和改进的模糊控制理论,提出了一种不依赖精确数学模型的智能复合控制算法。该算法采用直接力与气动力并联的复合策略,首先利用自适应遗传算法设计复合控制分配算法,然后基于变论域自适应模糊控制理论设计姿控发动机点火算法,最后考虑了姿控发动机离散点火特点,利用脉冲调宽调频(Pulse-width pulse-frequency,PWPF)方法对点火算法进行实现,并分析了系统的稳定性。仿真结果验证了该算法的有效性。Aiming at the characters of large jet interaction for missile with lateral jets and aerodynamic surfaces,an intelligent compound control algorithm based on adaptive genetic algorithm and improved fuzzy control theory is proposed,which don’t relay on an accurate mathematical model. The algorithm adopts parallel strategy of lateral jets and aerodynamic surfaces. Adaptive genetic algorithm is used to design compound control allocation algorithm. Ignition algorithm of attitude control engines is designed based on the variable universe adaptive fuzzy control theory. Considering the discrete ignition character of attitude control engines,the pulse-width pulse-frequency（PWPF） method is used for application and stability of the system is analyzed. Simulation results verify the ef-fectiveness of the algorithm.
