摘要: This paper presents a Direct Torque Control (DTC) utilizing 5-level cascaded H-bridge multilevel inverter (CHMI) for induction machines. A hysteresis controller flux and torque, with 12-sector stator angle detection precise look-up table optimum vector selection is proposed to enhance DTC performances. theoretical concept of the system in terms torque control estimations optimal voltage are studied this work. The simulation results obtained from MATLAB/Simulink software showed that significantly improved drive dynamic performance, smaller ripple lower THD.
