Induction motor drive predictive direct torque control method

Abstract

The paper deals with development of the induction motor drive direct torque control (DTC) based on the next step voltage vector prediction. The principle of the method is explained and the system mathematical description is provided. The derived control algorithm is implemented both in the simulation software MatLab/Simulink and on the real induction motor drive with dSPACE control system. Simulated and measured results in steady states and transients are presented.

Performance enhancement in a multilevel inverter fed PTC induction motor drive by optimal voltage vector selection

“…Predictive control scheme associated with DTC described in [10,11] diminishes both torque and flux ripples; it makes multiple predictions within one sampling interval. The proposed predictive algorithm in [12] has distinctly two parts: the first part arrives at the predictive stator reference flux vector; the second part aids the drive in tracking the stator reference flux by selecting either a zero voltage vector or an active vector.…”

Reduction of Ripple for Direct Torque Controlled Three Phase Induction Motor Based on a Predictive Control Technique

“…In the last decades, different methods have been proposed to deal with the problems of classical direct torque control(DTC), like using space vector pulse width modulation (SVPWM) [1], multilevel inverter applications [2] and model predictive control (MPC) [3]. Recently, MPC introduced an effective method to deal with classical DTC and takes allot of attention in both industrial and academic communities [4][5][6][7].In general, the MPC applications in electrical drives are classified in two types, model predictive current control (MPCC) [8,9] and model predictive torque control (MPTC) [4,7].…”
