新型变滑面导弹控制系统设计

在证明了过载的导数与角加速度存在近似比例关系的基础上,利用可以测量的线加速度和角加速度信号对过载系统进行了控制器的设计。为了提高控制器的性能,提出了一种变滑模面的滑模控制方法,并且用李雅普诺夫稳定性理论证明了系统的稳定性。仿真结果证明,采用变滑模面能保证跟踪误差较快收敛到零,并且系统输出的振颤大大减弱,同时该控制系统对参数摄动具有很强的鲁棒性。

New Approach of Variable Sliding-surface Controller Design for Missiles

When the derivation of overload of missile is proved to be approximately proportional to the angular acceleration, the design of a controller of the overload system is designed using the measurable signals of linear acceleration and angular acceleration. To improve the performance of the controller, a design scheme of variable sliding-surface is proposed, and Lyapunov stability theorem is used to prove the stability of the system. The simuktion results show that the tracking error converges to zero quickly and the chattering effect is much alleviated for the adoption of variable sliding-surface, besides the system is proved to be very robust to parameter perturbations.
