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.
In this paper, the characteristics and existing problems of traditional dynamic inverse control of BTT (Burn-To-Turn) missile are analyzed in detail, and then a decoupling compensation control method based on incremental model is proposed. By setting up an incremental model of BTT missile that describes the current dynamic transfer to the expected dynamic, the model part which is hard to measure or indeterminate is eliminated. Based on this, the incremental solution of BTT missile is designed based on dynamic inverse control In order to further improve the adaptability of the control system to the interference, a simple interference estimation / compensation strategy is proposed. Finally, through the mathematical simulation The validity of this method is verified.
