摘　　要：针对BTT(Bank-to-Turn)导弹的传统模型,建立过载跟踪模型,并基于模型中的强耦合问题,设计自抗扰解耦控制器。对于耦合通道,用自抗扰解耦控制器进行解耦,加入非奇异终端滑模控制器;对于无耦合通道,设计非奇异终端滑模控制器。实验仿真结果表明,新的控制策略结合了自抗扰的强鲁棒性与非奇异终端滑模的有限时间收敛能力,具有较好的动态性能和稳态性能,对指令进行有效的跟踪控制。An overload tracking model was established, based on the traditional model of BTT （Bank-to-Tum） missile, and an ADRDC （active disturbance rejection decoupling controller） was designed because of the strong coupling problem in this model. For the coupled channel, the decoupling was performed by the ADRDC, and then the NTSMC （non-singular terminal sliding mode controller） was added. For the non-coupled channel, only the NTSMC was designed. The experimental results show that the new control strategy can combine the strong robustness of ADRDC with the finite time convergence ability of NTSMC. Besides, it shows good dynamic performances and steady-state performance and is effective in tracking control.
