Design of an LMI-Based Fuzzy Fast Terminal Sliding Mode Control Approach for Uncertain MIMO Systems

This paper proposes a linear matrix inequality (LMI)-based fuzzy fast terminal sliding mode control (FFTSM) approach for multi-input multi-output (MIMO) system. design aims to achieve the finite-time convergence of system trajectories their desired values, while at same time eliminating chattering problem. Finite-time stability is proven using Lyapunov theory and parameters are obtained LMI approach. The logic considered fine tune controller reduce tracking error signal amplitude. performance proposed assessed simulation study direct current (DC) motor. results confirm effectiveness design. Simplicity design, robustness, convergence, chattering-free dynamics among features
