Abstract
In this paper, an uncertainty and disturbance estimator (UDE)-based control is employed to ensure the finite-time tracking and disturbance rejection performance for a class of Takagi–Sugeno fuzzy switched systems including additive time-varying delays, unknown time-varying uncertainties and disturbances. To be precise, the robust tracking performance is achieved by estimating unknown uncertainties and disturbances with the aid of low-pass filter by means of appropriate bandwidth choice of the desired filter. Moreover, a new delay-dependent finite-time stability criterion is derived by employing fuzzy-dependent Lyapunov–Krasovskii functional, extended Wirtinger's integral inequality and average dwell-time approach to enforce the addressed system to track the given reference system within a finite period of time. Finally, the developed theoretical results are ensured by presenting the numerical examples with simulation results.
