Fault-tolerant control design based on adaptive dynamic sliding mode technique for near space vehicles

In this paper, a novel adaptive dynamic sliding mode (ADSM) fault-tolerant control (FTC) methodology is developed for near space vehicle attitude control systems with actuator faults. The proposed ADSM approach which combines dynamic sliding mode with adaptive control strategies can make the systems...

Summary:In this paper, a novel adaptive dynamic sliding mode (ADSM) fault-tolerant control (FTC) methodology is developed for near space vehicle attitude control systems with actuator faults. The proposed ADSM approach which combines dynamic sliding mode with adaptive control strategies can make the systems stable and accurately track the desired signals in presence of external disturbances, model parameter uncertainties and even actuator faults. Firstly, the faulty attitude dynamic model of X-33 is introduced, and then the ADSM control and fault-tolerant control laws are designed for outer-loop and inner-loop respectively. Finally, simulation results are provided to show the effectiveness of the proposed FTC scheme.
