Abstract

Abstract: A new sliding mode observer design scheme is developed with a novel linear sliding manifold for the exponential stabilization problem of a class of uncertain switched systems in this note. Firstly, the linear sliding manifold is constructed based on a modified observer, through which a new technical approach of the underlying system analysis is exploited to devise a novel exponential stability criteria. Moreover, an associated adaptive switching controller is presented, by which the arrival condition of the designated sliding manifold is fulfilled. Ultimately, illustrative examples are conducted to confirm the feasibility of the proposed scheme. Highlights: A modified observer is established without any control inputs and/or compensator. A novel linear sliding manifold is constructed for the system. A new sufficient stability criteria during the sliding manifold is found. A new adaptive controller is developed to accommodate the presented strategy.
