针对高速旋转弹姿态控制系统存在的模型不确定、非线性、强耦合等问题，提出了基于变论域模糊控制的参数自适应姿态控制算法. 在建立姿态控制模型并通过前置反馈补偿方法对俯仰偏航通道进行解耦的基础上，利用变论域模糊控制器对姿态闭环反馈控制系统参数进行在线自适应整定. 仿真结果表明:变论域模糊控制器能有效改善闭环反馈控制系统的动态响应特性，减小弹体参数时变对控制器性能的影响，提高其适应性. 

Attitude Control Algorithm for High Spin Projectile Based on Variable Universe Fuzzy Control

Aiming at the problems of model uncertainty, nonlinearity and strong coupling in the attitude control system of high-speed rotating projectile, a parameter adaptive attitude control algorithm based on variable universe fuzzy control was proposed. On the basis of establishing the attitude control model and decoupling the projectile pitch and yaw channels by pre-feedback compensation method, the parameters of the feedback control system were adjusted online using the variable universe fuzzy controller. The simulation results show that the variable universe fuzzy controller can effectively improve the dynamic response characteristics of the closed-loop feedback control system, reduce the influence of time-varying missile parameters on the controller performance, and improve its adaptability.
