Enhancement of Induction Motor Dynamics Using a Novel Sensorless Predictive Control Algorithm

The paper introduces a novel predictive voltage control (PVC) procedure for sensorless induction motor (IM) drive. In the constructed PVC scheme, direct and quadrature (d-q) components of applied voltages are primarily managed instead controlling torque flux as in classic (PTC) technique. theoretical basis designed is presented explained detail, starting from used cost-function with its relevant components. A comprehensive performance comparison established between two controllers, which superiorities over PTC approach can be easily investigated through reduced ripples, computation time, faster dynamics. To sustain system’s reliability, combined Luenberger–sliding mode observer (L-SMO) verified different operating speeds controllers. Luenberger component concerned estimating stator current, rotor flux, speed. Meanwhile, sliding term to ensure robustness against any disturbance. verification PVC’s validity outlined performing analysis using Matlab/Simulink software. results illustrate that IM dynamic significantly improved when considering compared dynamics under PTC. addition, L-SMO has effectively proved ability achieve definite parameters variable estimation.
