Nonlinear systems modeled in the Takagi-Sugeno (T-S) form are studied. A T-S proportional observer is first issued by pole-placement and LMI tools. Secondly, time-varying change of coordinates for each dynamic state estimation error is used to design an interval observer. The system state bounds are then directly deduced.}, title={An interval observer design for uncertain nonlinear systems based on the T-S fuzzy model}, URL={http://ochroma.man.poznan.pl/Content/104487/PDF/acsc-2017-0025.pdf}, doi={10.1515/acsc-2017-0025}, }
