Abstract

This work investigates both Direct Torque-Flux Control (DTFC) and Deadbeat current control (DBC) methods with space vector modulation (SVM) for induction motor fed by three-level NPC power converters. The underlying control schemes share certain similarities, such as, fixed switching frequency, reduced inner loop control structure and fast dynamics in comparison with the conventional field oriented control technique. Experimental results further confirm that for induction machine control, nice control performances, both at transient and steady states, are seen when applying such strategies. However, DBC has a (slight) steady status tracking error in the (inner) excitation current and torque control loop due to its sensitivity to parameter deviations, while for these variables DTC scheme is error-free.
