Design of uncertainty and disturbance estimator based tracking control for fuzzy switched systems

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