Finite-time H∞ reliable control for T–S fuzzy systems with variable sampling

This work mainly concentrates on the finite-time H∞ reliable control for T–S fuzzy systems with aperiodic sampling. By considering the information of the state, an improved Lyapunov–Krasovskii functional (LKF) is structured. Moreover, based on free-weighted method and aperiodic sampling techniques, further criteria are proposed to guarantee that the T–S fuzzy systems is finite-time stabilization with H∞ performance. Meanwhile, the H∞ reliable controller is designed with larger sampling interval. Finally, the advantages of the obtained results are affirmed by a truck–trailer system.
