Latest Advances in DTC Control of Induction Motors

Abstract

In these days, developments in the area of Induction Motor control is increasing significantly. Considerable advancements have been taken place in the area of Direct Torque Control (DTC), which is capable of providing quick dynamic response with respect to torque and flux. This paper presents a detailed survey on various latest techniques of DTC control of Induction Motor such as DTC-SVM with hysteresis band, DTCSVM with Model Predictive Control, DTC with sliding mode control, DTC with Model reference adaptive system (MRAS) et cetera. The simulation results are discussed for DTC-SVPWM topology and results obtained proves that this method has reduced torque ripple

Optimal DC Voltage Control of a Photovoltaic Water Pumping System for Induction Motor Applications

“…Figure 6 demonstrates the use of DTC-SVM to assess the reference voltage vector and modify it via the employment of the SVM approach, resulting in the generation of inverter switches. The DTC-SVM arrangement eliminates the hysteresis controllers and the look-up database, therefore mitigating the associated downsides [36].…”

Developing and Implementing the Performance of Induction Motors Used in Well Pumping Systems

“…The speed error, which is handled by the PI speed controller, determines the torque reference (𝑇 𝑒 * ). The PI flux controller and PI torque controller are responsible for making the command voltages 𝑉 𝑑𝑠 and 𝑉 𝑞𝑠 , respectively [29]. In the instance of the two-level inverter, space vector switching attempts to match the sinusoidal reference voltage to the six active space vectors and two zero-voltage vectors generated by the inverter, as seen in Figure 8.…”
