Direct Torque Control for Induction Motor Using SVPWM Technique
Induction machine drive based on Direct Torque Control (DTC) allows high dynamic performance with very simple hysteresis control scheme. Conventional Direct Torque Control (CDTC) suffers from some drawbacks such as high torque ripple and variable switching frequency , difficulties in torque as well as flux control at very low speed. This paper is aimed to analyze DTC principles, the strategies ...
متن کاملRobust sliding mode speed controller for hybrid SVPWM based direct torque control of induction motor
The conventional direct torque control (CDTC) is known to produce quick and robust response in induction motor drives. However, during steady state, torque, flux and current occur, which results in acoustical noise and incorrect speed estimations. The main objective of this paper is to present different hybrid space vector PWM (HSVPWM) methods for direct torque controlled induction motor for re...
متن کاملPermanent Magnetic Synchronous Motor Control System based on ADRC
Permanent magnetic synchronous motor (PMSM) is a strong coupling and non-linear system. In the PMSM speed-regulation system, PID controller is the conventional one, it is difficult to decide the parameters of PID. Moreover, the performance of PID controller is not very well in large disturbance. In the paper, the Active Disturbance Rejection Controller (ADRC) is applied to the PMSM speed-regula...
متن کاملEKF BASED SPEED SENSORLESS DIRECT TORQUE CONTROL SYSTEM FOR IMs
In this study, it is aimed to design a speed sensorless DTC system for induction motors (IMs). All the states required for DTC system in addition to the load torque are estimated using an Extended Kalman Filter (EKF). Simulation results demonstrate a good performance and robustness.
متن کاملImproved Direct Torque Control for Induction Machine Drives Based on Fuzzy Sector Theory
Here, a new fuzzy direct torque control algorithm for induction motors is proposed. As in the classical direct torque control, the inverter gate control signals directly come from the optimum switching voltage vector look-up table, the best voltage space vector selection is a key factor to obtain minimum torque and flux ripples. In the proposed approach, the best voltage space vector is sel...
