To ensure the stability and safety of hypersonic vehicle reentry flights, we have designed a fault-tolerant integrated guidance and control (FTIGC) system using active disturbance rejection control (ADRC) theory. This system takes into account the presence of multiple uncertain factors and potential actuator malfunctions, which could compromise the vehicle’s trajectory. First, to tackle the issue of error caused by the association between individual guidance and control loop designs, a 6 DOF model of hypersonic vehicles and fault model of actuator are established. Then, predictor-corrector guidance law based on quasi-equilibrium glide condition (QEGC) is employed in guidance loop. In fault-tolerant control system, active disturbance rejection controllers are designed in attitude loop and angular loop respectively. Finally, under the condition of without and with actuator faults, the simulations are conducted. The effectiveness of the FTIGC system based on ADRC theory is verified through the simulation result.
