A modified DTC is proposed in this paper for the induction motor, driven by a cascaded three-level inverter, that gives superior torque performance compared to the use of Field Oriented Control (FOC) under transient conditions.Abstract:
Direct Torque Control (DTC) of induction motor is a scalar control technique that gives excellent torque dynamic performance. Deriving the advantages of multilevel inverter, a modified DTC is proposed in this paper for the induction motor, driven by a cascaded three-level inverter. The proposed DTC gives superior torque performance compared to the use of Field Oriented Control (FOC) under transient conditions. The ruggedness of the proposed control scheme using the cascaded inverter is tested for speed change, speed reversal and also torque change commands. The envisaged DTC is simulated using Matlab/Simulink and experimentally validated using a laboratory prototype.read more
