Finite Set Predictive Torque Control Approach of Induction Motor Fed by PWM Voltage Source Inverter

This paper investigates the application of finite set model predictive torque control (FS-PTC) for induction motor (IM) drives powered by pulse-width modulation voltage source inverter (PWM-VSI). Compared to traditional methods such as field-oriented control (FOC), FS-PTC offers superior dynamic performance, enhanced control precision and simplicity in handling system’s nonlinearities. The proposed approach uses the system's mathematical model to calculate future behavior and solve a multi-objective cost function, enabling optimal values of the controlled variables. In order to validate its effectiveness, extensive simulations were conducted in the MATLAB/Simulink environment under various operating conditions, including external disturbances, speed reversal, and parameter mismatches at low-speed operation. The findings highlight the FS-PTC's ability to provide accurate reference tracking, reduce torque ripples, and ensure robust performance despite parameter uncertainties.
