Model predictive control-based direct torque control for matrix converter-fed induction motor with reduced torque ripple

To reduce the torque ripple in motors resulting from use of conventional direct control (DTC), a model predictive (MPC)-based DTC strategy for matrix converter-fed induction motor is proposed this paper. Two new look-up tables are proposed, these derived on basis electromagnetic and stator flux using all feasible voltage vectors their associated switching states. Finite set (FCS-MPC) has then been adopted to select optimal state that minimizes cost function related torque. Finally, experimental results shown verify reduced performance MPC-based method.
