摘要：In this paper, the problem of state and input estimation for linear singular systems with unknown inputs is concerned. An equivalent standard state spaces system is derived for the purpose of the observer design. The necessary and sufficient conditions for the existence of the observer and the simple method to design the observer are given. The robust stability of the closed-loop obtained by dynamic output feedback is also discussed.
