It is well understood that Vector control (VC) scheme is very co mplicated and has slower torque response. Direct torque control (DTC) scheme is easier and has faster torque response, but it'll bring the bigger torque ripples than those under VC. In this paper, a new fuzzy logic VC-DTC torque control scheme based on the common of vector control and ...

Vector Control vs Direct Torque Control comparative evaluation for PMSM drive
2010 Joint International Conference on Power Electronics, Drives and Energy Systems & 2010 Power India, 2010This research article deals with the two closed loop speed control techniques namely Vector Control and Direct Torque Control for Permanent Magnet Synchronous Motor Drive. These two control techniques are critically evaluated for the performance comparison in terms of starting response, steady state response and transient condition.

Speed sensorless torque closed-loop vector control of IPMSM
2014 International Power Electronics and Application Conference and Exposition, 2014The speed sensorless control method, which is based on the extended electromotive force (EEMF) model of interior permanent magnet synchronous motor, is difficult to make into use and its parameter dependence is strong. So a method to simplify the EEMF model was proposed and a simplified full order state and sliding mode observer (FOSSMO) was designed ...

Torque Vectoring Control for Handling Improvement of 4WD EV
Advanced Materials Research, 2013Exploiting the structural merit that electric motors can be controlled precisely in speed und torque, this paper investigates the use of Torque Vectoring Control (TVC) for improving handling of electric vehicles. The strategy consists of two control levels. The upper level controller layer achieves reference yaw rate tracking, by using the 2-DOF planar

Torque-Vectoring-Based Vehicle Control Robust to Driver Uncertainties
IEEE Transactions on Vehicular Technology, 2015Driver-in-the-loop stability is a central issue in vehicle control systems. However, since a general human behavior model to explore it in a quantitative fashion has been lacking, little is known about how the vehicle can be controlled while considering the driver effects.

Vector and direct torque control of induction machines
1998Abstract Induction machines have been used for over a hundred years. Because of their simplicity, ruggedness, reliability, efficiency, low cost, compactness, and economical and volume manufacturing advantages, induction machines with a squirrel cage rotor are the most widely used machines at fixed speed. This is especially the case at

Space Vector Modulated Direct Torque Control for PMSM
2011It always exists that there are big ripples on flux linkage and electromagnet torque in traditional direct torque control (DTC) system. The implement of space vector modulation (SVM) was researched in-depth. The optimum combination of the fundamental voltage space vector was obtained according to the current expected voltage vector so as to compensate ...

Stator Voltage Vector Direct Torque Control of induction machine
2012 15th International Power Electronics and Motion Control Conference (EPE/PEMC), 2012This paper presents improved high speed Induction Motor (IM) torque control algorithm that achieves full inverter voltage utilization in field weakening and smooth speed transition from the base speed to high speed region. The Stator Voltage Vector Direct Torque Control (SVV DTC) algorithm simultaneously controls IM torque and rotor flux by regulating ...
