“…RCS jets produce discrete rather than continuous moments. 24 However, the utilization of RCS jets will consume more fuel. Therefore, under the premise of providing sufficient torque, RCS jets should be used as little as possible.…”

This study investigates the nonlinear fault detection and control allocation of a hypersonic re‐entry vehicle with intermittent faults and disturbances. The uncertain external disturbances in the inner loop system are processed on the basis of the studied intermittent fault mode. A set of residuals is generated by sliding time windows, and two hypothesis tests based on the residual mean are proposed to detect the appearance and disappearance of faults. An augmented observer is used to estimate the faults subject to the L2‐gain disturbance rejection constraint. A nonlinear backstepping fault‐tolerant control is designed to generate the desired control torque and make the output attitude track the given signal. An optimization control allocation algorithm distributes the desired torque to aerodynamic surfaces and reaction control system jets. The stability of the schemes is analyzed by Lyapunov and linear matrix inequality theories. Numerical simulation and rapid prototyping results are presented to demonstrate the validity of the proposed methods.

“…Through engineering experience, the distribution law is sufficiently demonstrated in literature [8] by using fuzzy logic control method. In literature [9], a segmented function is designed to distribute moment, and the RCS gradually exits with the reentry process, so that the pneumatic rudder works.…”

“…In addition, [11,12] mentioned that the installation position and angle of thrusters have different influences on the moment generated by the center of mass, and the components of each thruster are obtained to the HV through the decomposition of thrust. In [9] it also discusses the hysteresis characteristics of the discrete switch of the thruster, therefore PWPF is adopted to optimize and reduce the switching times.…”

In order to solve the problem of insufficient aerodynamic moment caused by thin air in the re-entry stage of hypersonic vehicle, this paper establishes an attitude angle model of hypersonic vehicle with reaction control system (RCS), and derives its affine linear model to decoupled the internal and external loop. According to the dead zone and saturation characteristics of RCS thruster, a control method to convert continuous moment into discrete switching instruction using pulse width modulation (PWM) is proposed. Since the number of thrusters is usually redundant, the installation matrix of thrusters in the body coordinate is established, and the command moment is coordinately distributed to the individual thrusters. Then a double-loop sliding mode controller (DSMC) is designed to achieve attitude stability and trajectory tracking. Finally, the simulation results show that DSMC has higher maneuverability, fewer thruster switches and stronger robustness to interference.
