Finite-Frequency H_/H∞ Fault Detection for Discrete-Time T-S Fuzzy Systems With Unmeasurable Premise Variables.

This paper investigates a finite-frequency $H_{-}/H_{\infty }$ fault detection method for discrete-time T–S fuzzy systems with unmeasurable premise variables. To minimize the effect of uncertainties on system performance and maximize that of actuator faults on the generated residual, both the $H_{\infty }$ disturbance attenuation index and finite-frequency $H_{-}$ fault sensitivity index are...
