摘　　要：模糊控制系统设计简单,对系统的不确定性和内外干扰具有较强鲁棒性,但是稳态精度差,尤其是在平衡点附近存在盲区。为了弥补不足,将模糊控制和经典PD控制相结合,提出一种模糊PD姿态控制系统设计方法,设计了运载火箭姿态控制系统。The fuzzy control system is simple in design,and robust to system uncertainty and internal and external disturbances,but its steady-state accuracy is poor,especially in the vicinity of the equilibrium point.In order to make up for the shortcomings,a fuzzy PD attitude control system design method is proposed with fuzzy control and classical PD control combined to,and the launch vehicle attitude control system is designed.
