摘　　要：针对不确定非线性强耦合BTT导弹的控制器设计问题,将滑模控制与反演控制思想相结合,在标称模型的基础上进行反演控制器设计。针对系统所存在的模型不确定性和外界干扰,增加一个积分滑模补偿器,提高系统的鲁棒性能。该方法通过合理地设计积分滑模面,保证系统初始状态处于滑模面上,消除了滑模到达阶段,从而有效地提高了系统的鲁棒性。仿真结果表明,该方法能够保证控制效果不受参数摄动和外界干扰的影响,从而满足工程实际的需要。The sliding mode control and backstepping technology are combined to solve control design problem of bank-to-turn missiles with model uncertainties and strong coupling nonlinear dynamics.First,the backstepping controller is designed based on the nominal model.Then,a compensator based on integral sliding mode surface is used to improve robustness to the model uncertainties and external disturbances.The sliding mode surface is properly designed so that the system can always start at the sliding mode surface.Because the reaching phase is eliminated,the sliding mode exists from the very beginning and the system is more robust against perturbations than the other sliding mode control systems with reaching phase.The simulation results indicate that the method can make sure that the control performance is robust against the parameter perturbations and meet the demand in practice.
