The finite-time convergence problem of an nth nonlinear system with unmatcheddisturbance is primarily studied in this paper. during the recursive procedure, a new finite-timecontroller is designed and proven by adding a sign function and a power integrator. Meanwhile, a C1 positive definite and proper Lyapunov function, which satisfies the finite-timeLyapunov stability law, is designed. Finally, the designed finite-time controller is appliedto some examples and an application of integrated guidance and control system to testand verify its advantage and practicability.

Owing to the dynamical, heterogeneous, complex anddistributed attributes of grid information, it is hard to make a normal and uniform description. How to construct an overlay structure to support the standardized modeling is a key research matter. In this paper, we describe an extensible framework for grid information service virtualized process. We begin the study with grid information and service virtualization. Then the grid information service virtualized process is divided into three levels: category, cluster and service, in which the construction and maintenance methods are studied. The grid information joining, leaving and updating are also analyzed. Finally, the space and time complexities are analyzed, and conclusions and future work are made.
