Many control methods are used in attitude control of reentry vehicle, such as optimal control and classical control methods. However, those control laws may not work effectively if the attitude system is confronted with actuator faults and saturation. This paper proposes an adaptive fault tolerant attitude control method for the reentry vehicle's attitude control system, by combining the radial basis function network technology with adaptive fault tolerant control method. We simultaneously considered actuator fault, actuator saturation, time varying unknown disturbances and uncertainties when designing the control method. First, we set up the reentry attitude dynamic model concerning actuator fault; second, a finite-time H∞ adaptive fault-tolerant attitude controller is introduced to deal with the actuator fault, saturation, unknown disturbances and uncertainties of the reentry vehicle system; we proved the stability of our proposed adaptive attitude fault-tolerant controller through the Lyapunov function and the linear matrix inequality method. Finally, the effectiveness of such adaptive fault-tolerant control method has been identified by numerous simulation results. The simulation results show that our proposed method can not only effectively deal with actuator fault in the attitude control system, but also has very good robustness for actuator saturation, time varying unknown disturbances and uncertainties.

“…These types of transportation systems are partially reusable, and they are technically not too challenging and seem suitable to be targets for research activities in the next decade. 6) After separation, RBV needs to flyback to the launch site or special landing area. In the projects mentioned above, the RBV is launched vertically and lands on a normal runway horizontally, such as the concepts presented by the ESA 2,7) and JAXA 4) in Fig.…”

Taking the engineering application of reusable booster vehicles (RBVs) as the research background, an effective navigation system scheme for rocket-powered auto-flyback RBVs is put forward in detail. First of all, the research state of RBVs in main research departments and three kinds of typically used feasible flyback options for RBVs are introduced. Based on an analysis of the characteristics of application background and engineering requirements, a feasible navigation scheme for a rocket-powered auto-flyback RBV is put forward, which consists of a strapdown inertial navigation system (SINS), global navigation satellite system (GNSS) and radio navigation equipment (radio). In order to realize navigation with high accuracy and dynamic adaptability, an improved dynamic information integration strategy is used for the navigation system, and simulation of the scheme based on a special trajectory is carried out. The theoretical analysis and simulation results indicate the effectiveness and feasibility of the navigation technologies.
