Minimum eigenvalue based adaptive fault compensation for hypersonic vehicles

The attitude tracking control problem is addressed for hypersonic vehicles under actuator faults that may cause an uncertain time-varying gain matrix. An adaptive compensation scheme developed to ensure system stability and asymptotic properties, including a kinematic signal dynamic signal. To deal with the uncertainties of matrix, new positive definite one constructed. minimum eigenvalue such matrix estimated. Simulation results application X-33 vehicle model verify effectiveness proposed based fault scheme.
