Abstract
In this study, a new fault tolerant control approach is proposed for a class of reusable launch vehicle (RLV) attitude control systems. The nonlinear attitude control systems of RLV are given, which represent the dynamic characteristics of RLV in ascent and reentry phases. When actuator loss-of-effectiveness (LOE) faults occur, a new fault tolerant control design is presented using the dynamic surface control technique. Based on Lyapunov stability theory, the ultimate uniform boundedness of the faulty attitude control systems of RLV is analyzed. Finally, simulation results are given to illustrate the efficiency of the proposed approach.
