Predictive Torque Control of an Induction Machine - Voltage Source Inverter System

Predictive control techniques have emerged as a suitable solution for the control of motor drive systems. In this paper, a predictive control strategy for the flux and torque control of an induction machine fed by a voltage source inverter is presented. The algorithm selects an available commutation state for the converter which minimizes a cost function, and this state is applied in the next sampling time. Simulated results from Matlab/Simulink demonstrate the feasibility of the strategy showing a good tracking of the variables to their respective references and sinusoidal motor stator currents.
