While sliding mode observers (SMOs) using discontinuous relays are widelyanalyzed, most SMOs are implemented computationally using a continuousapproximation of the discontinuous relays. This approximation results in theformation of a boundary layer in a neighborhood of the sliding manifold in theobserver error space. Therefore, it becomes necessary to develop methods forattenuating the effect of the boundary layer and guaranteeing performancebounds on the resulting state estimation error. In this paper, a method isproposed for constructing boundary-layer SMOs (BL-SMOs) with prescribed stateestimation error bounds. The BL-SMO formulation is then extended tosimultaneously estimate exogenous inputs (disturbance signals in the state andoutput vector fields), along with the system state. Two numerical examples arepresented to illustrate the effectiveness of the proposed approach.
