Resumen
Descripción
In this paper a sliding-mode observer for linear time-invariant systems is proposed. The observer is based on integral sliding modes and the equivalent control method. In order to induce a sliding mode in the output error, a second order sliding mode algorithm is used. Convergence proofs of the proposed observer are presented. In order to expose the features of this proposal, a design example over a DC motor model is exposed, noiseless and noisy measurements cases are considered. For this case, the simulation shows the high performance of the integral observer.
