Reduced-order observer design for a class of switched singular systems

This paper studies reduced-order observer design problems for a class of switched singular systems with unknown inputs by average dwell time switching signals. The switched singular systems is first to be decomposed into a new equivalent form, and then a switched reduced-order observer is developed to asymptotically estimate the system states. In the end, the technique is applied to an electronic circuit model to demonstrate the merit and effectiveness of the proposed methods.
