Matrix Converter Induction Motor Drive Employing Direct Torque Control Method

The presented paper deals with the implementation of the Switching Table Based Direct Torque Control (ST-DTC) in the matrix converter-fed induction motor drive. In order to improve the control of the matrix converter input power factor, the use of the simplified Indirect Space Vector Modulation (ISVM) was proposed. To verify the feasibility of the proposed solution, experimental results were pr...

Direct Flux and Torque Control of Induction Motor Drive Changing the Hysteresis Band Amplitude

Direct Flux and torque control (DTC) based speed control strategy of induction motor (IM) drive and the effect of flux and torque hysteresis band amplitude on this strategy is presented. This scheme is simple and provides a good dynamic response. But the major problem associated with this DTC drive is high torque along with stator flux ripples. The direct torque control of induction machine is ...

Improved Direct Torque Control of Induction Motor Drive under Low Speed Operation

This paper presents a modified two level inverter topology to improve the low speed performance of the direct torque controlled (DTC) three phase induction motor drive. Proposed method is based on current ripple principle. In this technique, the inverter switching states are derived as a function of rotor speed. This method gives low ripple in flux and torque at low speed operation when compare...

Torque Ripple Reduction in Direct Torque Control Induction Motor Drive Using Svm and Fldrc

Direct Torque Control (DTC) is a control technique used in AC drive systems to obtain high performance torque control. The conventional DTC drive contains a pair of hysteresis comparators, a flux and torque estimator and a voltage vector selection table. The torque and flux are controlled simultaneously by applying suitable voltage vectors, and by limiting these quantities within their hysteres...

Torque Ripple minimization techniques in direct torque control induction motor drive

This paper considers direct torque control strategies in induction motor drive to minimize torque ripples. Spacevector modulation and modified space vector control concept is implemented to design the controller. Basic DTC method suffers from torque ripples problem and switching frequency variation.[1] Torque ripples are minimized using space vector modulation technique but execution time in th...
