The problem of pole assignment over a certain region of owning integrity is explored for linear continuous descriptor systems. Based on the generalized Lyapunov equation and generalized Lyapunov inequality, necessary and sufficient conditions are obtained for pole clustering inside a circular region with a proved bound. By means of a generalized Riccati inequality, a design method of controller for descriptor system with actuator failure is presented. The induced system possesses integrity against actuator failure. The designed state feedback controller resulting in closed loop system is regular, impulse-free and pole clustering inside a circular region, i.e. D-admissible. Under certain condition, the same control law guarantees the systems D-admissible.
