This paper discusses a new designing process of fault tolerant controller possessing integrity of a type of linear system with uncertainty using robust control results. When sensors or actuators experience outage, and the uncertainties of the system are of norm bounded, controller possessing integrity is designed by constructing an auxiliary system without uncertainties in term of the positive solution of Hamilton-Jacobi inequities. The method guarantees the close\|loop system is asymptotically stable with H performance. The approach presents a new way to solve the integrity control problem of a type of linear system with uncertainties.
