This paper presents the performance analysis of direct torque control (DTC) and DTC based space vector modulation (SVM) technique controlled induction motor drive. DTC drive utilizes hysteresis comparators and suffers from high torque ripple and variable switching frequency. While the SVM-DTC reduces torque ripple preserving DTC merits. SVM-DTC calculates the required voltage vector to compensate the flux and torque errors generating SVM for each sampling period. The simulation is performed using PSIM and shows the better performance of SVM-DTC over basic DTC.

Abstract:

Direct Torque Control (DTC) is considered one of the most effective methods for the decoupled control of electromagnetic torque and speed in an induction motor. In DTC, torque is directly regulated by the torque angle, defined as the difference between the stator flux angle and the rotor flux angle. The advantages of employing DTC include the simplicity of implementation, a reduced number of controllers, excellent torque dynamics, and decreased torque oscillation. Implementing DTC with microcontrollers is easier than with Field-Oriented Control (FOC). This paper discusses the operational princ

This paper presents the significant improvement of Direct Torque Control (DTC) of 3-phases induction machine using a Cascaded H-Bidge Multilevel Inverter (CHMI). The largest torque ripple and variable switching frequency are known as the major problem founded in DTC of induction motor. As a result, it can diminish the performance induction motor control. Therefore, the conventional 2-level inverter has been replaced with CHMI the in order to increase the performance of the motor either in dynamic or steady-state condition.

Abstract:

This paper describes a study of Switching Table Direct Torque Control (ST-DTC) and Fuzzy Rule based Direct Torque Control (FR-DTC) in case of a three phase induction motor. The hysteresis band and the switching table used in the ST-DTC scheme have been replaced by a Fuzzy Rule based controller in the FR-DTC. Results show that the FR-DTC method provides better transient performance compared to the ST-DTC method.

Abstract:

Conventional direct torque control (DTC) is one of the best control systems for regulating the torque of an induction motor (IM). However, the DTC’s enormous waves in flux and torque cause acoustic noise that degrades control performance, especially at low speeds due to the DTC’s low switching frequency. Direct torque control systems, which focus just on torque and flux, have been proposed as a solution to these problems. In order to improve DTC control performance, this work introduces a fractionalorder fuzzy logic controller method. The objective is to analyze this technique crit

Matrix converter is a good choice for Permanent Magnet Synchronous Motor (PMSM) drives, because it has high power density and does not require dc-link energy storage. the disadvantages of conventional matrix converter is using 18 active switches, so it becomes expensive and the modulation method becomes more complicated than back to back converter. To minimize this problem, this paper proposes variable speed drive of PMSM using Ultra Sparse Matrix Converter (USMC) based on Direct Torque Control (DTC) methods. This converter uses only 9 active switches, making it cheaper than conventional matri

Abstract:

A novel induction motor direct torque control (DTC) algorithm with synchronous modulation is presented. Compared to the traditional DTC method, whose main drawback is the presence of low-frequency torque harmonics (sub-harmonics), in the proposed method, the PWM switching frequency is imposed to be an integer multiple of the main supply frequency. This is achieved by continuously adjusting the PWM switching period to significantly reduce low-frequency harmonics. The devised algorithm has been tested on an inverter-fed induction motor drive system, and the obtained results show an important red

The inputs and output of the fuzzy controller are: stator flux, torque error, angle and amplitude of voltage vector in stator

By detecting motor’s stator voltage and current, along with calculating motor’s flux and torque in virtue of the instantaneous space vector theory, DTC controlled flux and torque directly according to the difference between the detecting value and design value. DTC also reduced calculation amount and overcomed the flaw that the system was disturbed by motor’s parameters easily, which were the problems in the vector control.

In this paper, a method of direct torque control (DTC) for permanent magnet synchronous motor (PMSM) based on fuzzy regulator is proposed. It overcomes the disadvantages such as speed drop with load, torque ripple etc., which happens in the DTC for PMSM based on conventional PI regulator. The simulation results show that, the DTC for PMSM based on fuzzy regulator can effectively improve the system loading capability and significantly reduce the torque ripple and the harmonic content of the system. Therefore, it can comprehensively improve the system performance.
