摘　　要：本文针对部分执行器失效情形下的三维鲁棒导引律设计问题,利用输入–状态稳定性原理,设计一种三维非线性自适应容错导引律.与已存在结果相比,所设计算法能够实现对部分执行器失效的自动补偿,并且具备克服机动目标未知机动性对制导效果的影响.理论分析和数值仿真验证了该算法的有效性,并且数值仿真还表明其能够恢复特定时间段内执行器完全失效时的系统稳定性,具有很强的鲁棒性.A three-dimensional adaptive fault-tolerant nonlinear guidance law is proposed based on input-to-state stability（ISS） for intercepting maneuvering targets. Compared with other existing methods, the proposed approach can realize the automatic compensation of the actuator failures, and compensate for the effects of the unknown target maneuvers. The theory analysis and the simulation results show the effectiveness of our scheme, and the simulation results indicate that the presented approach can achieve a successful interception with respect to the complete actuator failures within a certain period of time.
