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 the presented approach can achieve a successful interception with respect to the complete actuator failures within a certain period of time.
