变质心高速旋转弹的滑模姿态控制器设计

The Design of Sliding-mode Attitude Control of Variable Centroid High Spinning Projectile

针对采用变质心技术的高速旋转弹,考虑滑块的六自由度运动,基于牛顿力学建立了由炮弹和滑块组成的多体系统的动力学模型,并根据实际情况对模型进行了合理简化。以滑块的旋转角加速度为控制量,设计了具有鲁棒性的滑模变结构姿态控制器,使弹体实际姿态角能够快速跟踪理想姿态角。

Aiming at the high spinning projectile that adopted variable centroid control,considering the moving-mass moving at six degrees of freedom,based on Newton mechanics established the more systematically model of high spinning projectile that concluding movingmass and projectile,and simplified the model based on reasonable supposition and physical truth.Taking the angular acceleration of moving-mass as control part,based on the slide mode theory,the controller that have robustness is designed.The actual attitude angel of the high spinning projectile could follow the ideal attitude angel.
