Integral sliding‐mode‐based almost output regulation for switched T‐S fuzzy systems

Abstract This paper investigates the integral sliding‐mode‐based almost output regulation (SMBAOR) issue of switched T‐S fuzzy systems (STSFSs) with matched uncertainty. First, a switched fuzzy integral sliding mode (SM) surface is introduced. Based on the controller derived from the sliding mode surface and the multiple Lyapunov functions method, a solvability condition constrained by average dwell‐time (ADT) relevant switching index is established to achieve OR characteristic and performance. Then, the form of the SM control law that can guarantee the finite time reachability of the switched fuzzy integral SM surface is given. Further, the efficacy of the control tactic is verified by adjusting the total temperature increment of the low‐pressure turbine outlet of the aero engine model.
