摘　　要：针对通用高超声速飞行器的非线性模型,提出了一种单回路控制器的设计方法。控制系统由3个模糊控制器组成控制回路。基于遗传算法实现了模糊规则的自动优化,无需先验知识和训练样本。在控制飞行器轨迹、姿态和推力时,考虑了非线性动态特性、不确定性和约束。仿真表明,该方法能提供满意的鲁棒性和快速收敛的模糊规则。According to the nonlinear model of pitching channel of generic hypersonic vehicle,a single-loop flight controller is designed.The system is composed of three fuzzy controllers.Based on the genetic algorithm,the optimization process of fuzzy control rules is implemented automatically without experts knowledge and training data in advance.The nonlinear dynamics,uncertainties and restrictions are involved in research on the control of trajectory,attitude and thrust.The simulations show that the method is able to satisfy both the robustness of flight control system and the convergence of optimization process on request.
