Received Feb 13, 2017 Revised Apr 17, 2017 Accepted May 1, 2017 A Constant Switching Frequency Direct Torque Control (CSF-DTC) with low switching losses Space Vector modulation (SVM) for Permanent Magnet Synchronous Motor (PMSM) drive is proposed in this work. The CSF-DTC combines Field Oriented Control (FOC) and basic DTC advantages. Indeed, the proposed control strategy improves the basic DTC...

This paper aims to develop vector controlled permanent magnet linear synchronous motor (PMLSM) based on simplified space vector pulse width modulation. Mathematical models of PMLSM&SVPWM presented. The present PWM technique does not involve any sector identification and considerably reduces the computation time when compared to conventional space vector PWM technique. To validate the proposed a...

This paper presents a comparative evaluation of three phase Voltage Back to Back Converter (VBBC) and three phase Matrix Converter (MC)fed Induction Motor (IM) drive. These two topologies are developed using Space Vector Modulation (SVM) technique and simulated in MATLAB/SIMULINK. Both the topologies are functionally equivalent in terms of input power quality and energy regeneration capabilitie...

This paper proposes a hybrid carrier based space vector modulation suitable for multiphase multilevel inverters. Multiphase multilevel inverters are controlled by this hybrid modulation to provide multiphase variable voltage and variable frequency supply. The proposed modulation combines the benefits of fundamental frequency modulation and carrier based space vector modulation strategies. The m...

Fast speed drives for Permanent Magnet Synchronous Motor (PMSM) is a crucial performance for the electric traction systems. In this paper, PMSM is derived with a Model-based Predictive Control (MPC) technique. Fast speed tracking is achieved through optimization of the DC source utilization using MPC. The technique is based on predicting the optimum voltage vector applied to the driver. Control...

This article presents a single-shunt measurement of three-level inverter using modified space-vector modulation to reconstruct the three-phase load current. The proposed method was implemented on digital signal processor (DSP), and algorithm verified in laboratory experiment. Through work, it proven that current could be performed for inverters an analogous way ordinary inverters. Three-phase r...

In comparison to the original SVM, which involves a quadratic programming task; LS–SVM simplifies the required computation, but unfortunately the sparseness of standard SVM is lost. Another problem is that LS-SVM is only optimal if the training samples are corrupted by Gaussian noise. In Least Squares SVM (LS–SVM), the nonlinear solution is obtained, by first mapping the input vector to a high ...
