摘　　要：针对大气层内拦截导弹直接侧向力与气动力复合控制系统的设计问题,提出了基于鲁棒跟踪控制的复合控制策略,该策略利用直接侧向力控制快速跟踪指令过载,利用气动控制补偿导弹的气动阻尼力矩和气动静稳定力矩.根据过载指令设计过载回路鲁棒跟踪控制,给出期望的角速度,设计角速度回路,利用气动控制补偿模型已知部分,并设计直接侧向力鲁棒跟踪控制器跟踪期望角速度.仿真结果表明,依靠所给出的复合控制策略,可以有效抑制外部干扰和模型不确定性的影响,显著加快拦截导弹的过载响应速度.Aiming at the blended control system design of direct lateral thrust and aerodynamics of atmospheric interceptor, a robust tracking control strategy was proposed. The lateral thrust control system was used to track the command in order to obtain the fast response. The aerodynamic control system was used to compensate damping torque and static stability torque. The overload control loop was designed by robust tracking control, and the demanded pitch rate was obtained. The pitch rate loop was designed to track demanded pitch rate. Aerodynamic control system was used to compensate known part of the missile model, and a method based on robust tracking control was used to adjust the lateral thrust. Sim- ulation results show that by the proposed blended control strategy, the parameter uncertainties of the plant and lateral jet interaction can be restrained effectively, and the strategy overload command can be tracked with high precision and fast response speed.
