Abstract :
A design method of robust fault-tolerant control for control systems with uncertain parameters and perturbation has been deduced by utilizing H∞ theory and state-feedback control law with a state observer. The robust stability conditions for control systems with sensor failure have been obtained by solving two Riccati equations. Numerical example is given to illustrate the validity of the obtained results in this paper.
