discrete‐time non‐linear systems described by Takagi–Sugeno (T–S) fuzzy models using a
non‐monotonic Lyapunov approach. In the non‐monotonic Lyapunov approach, the
monotonicity requirement of the standard Lyapunov approach is not required. Based on the
non‐monotonic Lyapunov approach, sufficient conditions for the existence of an output
stabilising feedback controller for discrete T–S fuzzy systems with and without uncertainties …
