摘要

摘要: 详细分析了倾斜转弯(BTT, Bank-To-Turn)导弹传统动态逆控制的特点及其存在的问题,在此基础上提出了一种基于增量模型的BTT导弹解耦补偿控制方法.该方法通过建立一种描述从当前动态转移至期望动态的BTT导弹增量模型,消除了难以测量或不确定较大的模型部分;在此基础上结合动态逆控制思想设计了BTT导弹的增量式解耦跟踪控制律,与传统动态逆相比,该控制律对模型的依赖程度大幅降低;为进一步提高控制系统对干扰的适应性,提出了一种简单的干扰估计/补偿策略;最后通过数学仿真验证了该方法的有效性.

Abstract: The characteristic and existed problems of traditional dynamic inversion control for bank-to-turn (BTT) missiles were analyzed in detail. A novel decoupling-compensating control approach was proposed for BTT missiles. In this approach, an incremental BTT model which demonstrated the transition from current dynamics to desired dynamics was established. And by doing so, the portion of model which was difficult to observe or with large uncertainties was eliminated. Then based on the incremental model and dynamic inversion, the incremental decoupling-tracking control law was designed which relied less on model than the traditional dynamic inversion. To further improve the control law’s adaptability to disturbances, a simple disturbance estimation and compensation strategy was proposed. Finally, simulation results validate the effectiveness of this approach.
