Robust fault-tolerant H∞ control for hypersonic vehicle attitude control system

Robust fault-tolerant control problem is investigated for Hyper-X hypersonic vehicle attitude control system. Based on parameter-dependent Lyapunov functions, robust fault-tolerant H∞ static feedback controller is designed for actuator faults. The sufficient conditions, guaranteeing that the hypersonic vehicle is robust fault-tolerant stable with H∞ index constraints, are obtained for the design of static feedback controller in terms of linear matrix inequalities (LMIs). Finally, an application to numerical example shows the effectiveness of the proposed methods.
