The on-going electrification transportation system revolution has already started and the continuous evolution of power electronics allows new and more reliable system layouts and control strategies to be investigated. Mainly, this revolution is driven by increased reliability levels. Since multi-three phase motors are fault tolerant by definition, they are a very good candidate for more reliable...
A simple fault-tolerant induction motor drive with v/f speed control included in the electrical auxiliary equipment of railway locomotives is presented in the paper. The employment of fault tolerant on-board electrical auxiliary equipment increases the dependability and then the quality of the railway service. The fault tolerance technique consists of some emergency countermeasures applied in case...
In the steer-by-wire (SbW) system of new generation of vehicles the shaft of the conventional steering equipment is substituted by two electric drives. This article presents two schemes, termed torque and speed schemes, for the control of SbW system. The first scheme, designated with the torque scheme, is derived from the model of the conventional steering equipment, while the second one, designated...
