A Feedback Control Strategy for Torque-Vectoring of IWM Vehicles
Volume 3: 16th International Conference on Advanced Vehicle Technologies; 11th International Conference on Design Education; 7th Frontiers in Biomedical Devices, 2014In last decades hybrid and electric vehicles have been one of the main object of study for automotive industry. Among the different layout of the electric power-train, four in-wheel motors appear to be one of the most attractive. This configuration in fact has several advantages in terms of inner room increase and mass distribution.

Predictive Torque Vectoring Control with Active Trail-Braking
2018 European Control Conference (ECC), 2018In this work we present the development of a torque vectoring controller for electric vehicles. The proposed controller distributes drive/brake torque between the four wheels to achieve the desired handling response and, in addition, intervenes in the longitudinal dynamics in cases where the turning radius demand is infeasible at the speed at which the

Testing of a torque vectoring controller for a Formula Student prototype
Robotics and Autonomous Systems, 2019Abstract The torque vectoring controller is the electrical substitute of a mechanical differential, with the advantage of improving the stability and handling of the vehicle. This work tackles the design, implementation and testing of a torque vectoring algorithm to be implemented in a Formula Student prototype.

Torque vectoring for an electric vehicle using an LPV drive controller and a torque and slip limiter
2012 IEEE 51st IEEE Conference on Decision and Control (CDC), 2012This paper proposes a torque vectoring strategy for the propulsion of an electric vehicle with two independent electric machines at the front wheels. The torque vectoring controller includes a vehicle dynamics controller and a motor torque and wheel slip limiter.

Vector analysis of astigmatism changes by flattening, steepening, and torque
Journal of Cataract and Refractive Surgery, 1997To understand the effect of astigmatism surgery by analyzing astigmatic changes according to their component parts.Cheltenham Eye Centre, Melbourne, Australia.The component parts of the astigmatic changes considered were flattening, steepening, clockwise torque, and counterclockwise torque. Calculations to determine the astigmatic change were performed

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 ...
