摘要
基于反步设计法和输入-状态稳定理论,针对地面固定目标,提出了一种执行器失效时自适应导引控制一体化(IGC)设计方法。首先,描述了一体化导引控制的数学模型;然后,基于反步设计法提出一种导引控制一体化算法,该算法能够在额外扰动和执行器失效的情况下以设计的冲击姿态角打击地面固定目标;同时,提出一种自适应律来处理由于执行器部分失效所引起的不确定性。仿真结果表明该算法是行之有效的。
An adaptive integrated guidance and control (IGC) approach is proposed based on backstepping method and input-to-state stability for homing missiles against ground fixed targets with actuator failures. A model of the IGC system in the pitch plane is formulated. The IGC laws are designed via backstepping method, which can provide desired impact attitude angle to hit the fixed targets in the presence of external disturbances and actuator failures. In order to deal with the uncertainties, an adaptive control law is developed. The numerical simulation resuits demonstrate the effectiveness of the proposed design scheme.
