Abstract :
This paper handles the fault detection for the nonlinear systems described in Takagi-Sugeno (TS) form. The TS model is obtained by the sector nonlinearity transformation, representing in an exact way the nonlinear model in a compact of the state space. The used method of diagnosis is obtained by an analytical approach based on parity relations. The generation of residual signal is supplied by the linear matrix inequalities (LMI). An illustrative example is after retailed showing the efficiency of the work.
