Fault Tolerant Control of Drone Interceptors Using Command Filtered Backstepping and Fault Weighting Dynamic Control Allocation

This paper proposes a fault tolerant control strategy for drone interceptors with fixed wings and reaction jets subject to actuator faults. The have both continuous discrete actuators, which pose challenge the system design. proposed consists of two parts, nonlinear virtual law dynamic allocator. To deal uncertainty quantization error, parameter update is designed by command filtered backstepping. Then, weighting allocation algorithm developed distribute signal actuators on interceptor. When an occurs, scheme can redistribute signals remaining actuators. effectiveness confirmed numerical simulation.
