摘　　要：控制器性能的优劣是确保导弹能否在制导飞行中具有良好的稳定性和可控性的关键。不考虑通道之间的耦合,基于倾斜转弯(Bank-To-Turn)控制技术建立某型BTT导弹三通道弹体数学模型,分别设计了滑模变结构控制器并构造BTT导弹闭环控制系统,与PD控制和未加控制器时进行了对比研究。仿真结果表明,滑模变结构的控制效果更好,能快速跟踪导引指令,并具有良好的动态特性和稳态性能。The performance of the controller is the key to ensure the stability and controllability of the missile in guided flight. Without considering the coupling between the channels, we established a three-channel missile mathematical model for BTT missile based on Bank-To-Turn （BBT） control teehnology. The sliding mode variable structure controller was designed, and the closed-loop control system was constructed for BTF missile. Comparative study was made with PD control and the situation without the controller. The simulation results show that：the control effect of sliding mode variable structure is the best, which can quickly track the guidance command, and has good dynamic and steady-state performance.
