This paper presents a comparative analysis between conventional direct torque control (C_DTC), Modified direct torque control (M_DTC) and twelve sectors direct torque control (12_DTC).Those different strategies are compared by simulation in term of torque, flux and stator current performances. Finally, a summary of the comparative analysis is presented.
the aim of this paper is to presents a contribution for detailed comparison between fuzzy direct torque control (FDTC) strategy of Induction Machine (IM) using FLC and fuzzy logic switchers (FLS), and the conventional DTC using the two PI and IP controller. The performances of those two control schemes are evaluated and compared by simulation in terms of speed, flux, torque, current ripples and transient...
An improved and modified Direct Torque Control (DTC) algorithms for permanent magnet synchronous motor (PMSM) drive is investigated in this paper, which features low torque and flux ripple and almost fixed switching frequency. Indeed, a first algorithm uses DTC with Space Vector Modulation (SVM), which is called DTC-SVM, improves greatly the torque and flux ripples compared to the basic DTC reported...
Direct Torque Control (DTC) has becoming the industrial standard for Induction Machine (IM) torque control by means of very simple control schemes. This paper presents a contribution for detailed comparison of Direct Torque Control strategies (Classical DTC, SVM-DTC and Fuzzy DTC) for Induction Machine. The performances of those various methodologies are evaluated and compared by simulation in terms...
This paper presents a contribution for detailed comparison between two control strategies for Induction Machine (IM) drives: Direct Field-Oriented control (DFOC) and Direct Torque Control (DTC). The performances of those two control schemes are evaluated and compared by simulation in terms of sensitivity to machine parameters. Finally a summary of the comparison not only regarding the performance...
