英文摘要：

For nonlinear differential-algebraic equations sys- tem which is of index one and satisfies linear growth condition, it is shown that the problem of sampled-data output feedback sta- bilization control can be solved. A linear explicit non-initialized observer is proposed to obtain the state estimation. Then a lin- ear sampled-data output feedback controller is designed, through which the whole closed-loop systems are asymptotically stable. Simulation results show the validity of the control method pro- posed in this paper.
