Fuzzy Nonlinear Unknown Input Observer Design with Fault Diagnosis Applications

Chen, Weitian; Saif, Mehrdad


An approach for nonlinear unknown input observer (NUIO) design is proposed for a class of nonlinear systems representable by a Taka-Sugeno (TS) fuzzy system. The proposed NUIO design for TS fuzzy systems is carried out for two cases: (1) the premise variables do not depend on the unmeasured state variables; and (2) the premise variables depend on the unmeasured state variables. Sufficient conditions for the existence of NUIOs are derived, and a linear matrix inequality (LMI)-based design...[Show more]
