The main topic of this paper is the problem of step-by-step observer synthesis for Takagi-Sugeno fuzzy systems. First order and second order sliding mode observer are used for the finite time estimation of the state variables. Moreover, in this paper, two cases of Takagi-Sugeno systems are considered, with measurable and unmeasurable premise variables. Two simulation examples show the step by step finite time convergence of the estimation error. © 2013 IEEE.
