Enhanced Reaching-Law-Based Discrete-Time Terminal Sliding Mode Current Control of a Six-Phase Induction Motor

This paper develops an inner stator current controller based on enhanced reaching-law-based discrete-time terminal sliding mode. The problem of tracking currents with high accuracy while ensuring the robustness a six-phase induction motor in presence uncertain electrical parameters and unmeasurable states is tackled. unknown dynamics are approximated by using time delay estimation method. Then, power-reaching law used to make each stage convergence faster. A stability analysis system controller’s finite-time demonstrated detail. Practical work was conducted asymmetrical machine illustrate developed discrete approach’s effectiveness.
