Abstract
In this paper, a new extended sliding mode observer for second-order linear systems is proposed. It is shown that, when the sampling period is small enough, the unmeasurable state estimation errors can be numerically estimated and then used for constructing the switching functions of the sliding mode observer. The advantages of the proposed new sliding mode observer are that (i) it has a solid theoretical background of stability and convergence from the view-point of the observer-like system; (ii) it can sufficiently approximate the observer-like system when the sampling period is small enough; (iii) the fast error convergence is good for practical applications. Simulation results are given in support of the advantages and effectiveness of proposed new sliding mode observer.
