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.
