“…EV manufacturers prefer various electrical machines such as traction motors, switched reluctance motors, permanent magnet synchronous motors, induction motors, etc. Availability at the variable rating, low cost, and simple and magnet-less construction lead to the induction motor being one of the most suitable options for traction application [23][24][25][26][27]; however, fine control of the induction motor and loss of control at very low speed of the induction motor still form a significant problem; but field-oriented control (FOC) makes it possible to have decoupled control of torque and flux such as that in a separately excited dc motor. Space vector modulation (SVM) is an advanced control technique which controls the inverter in digital form.…”

An electric vehicle uses multiple energy-storage systems to power the traction motor. Dual-source inverters (DSIs) are used for single-stage power conversion by skipping the dc/dc boost converter stage; therefore, eliminating the passive magnetic storing element which improves the overall efficiency of the drive; moreover, multiple energy-storage systems improve the power density of the system. This article discusses the fine control of a traction motor from zero speed to rated speed supplied through a dual-source inverter. Field-oriented control with space vector modulation technique is applied to achieve closed-loop control. Two dc sources are used, one having a higher-voltage battery and one a lower-voltage battery. The higher-voltage battery is the main battery which supplies power to the traction motor, whereas the lower-voltage battery supplies power to supplementary loads of the EV. This article presents improved dynamic behaviour of an induction-motor-driven EV fed from a dual-source inverter using modified closed-loop field-oriented control with space vector modulation. The improvement includes reduced control complexity due to space vector modulation and achieving the option of EV operation in an emergent situation using the same converter and control system. The simulated performance of the presented system is obtained in MATLAB/Simulink. A step-down experimental prototype is used for verification of effective control of the induction motor as the EV is under constant torque variable speed operation with real-time parameters such as power, power factor, current harmonics, and voltage/current stresses across the switch using two batteries individually.

“…The controller confers an extremely rapid dynamic response. However, DTC has two weaknesses: the torque ripples are significant, especially when compared to the FOC, and the switching frequency is unpredictable and based on the hysteresis bands [7]. Resulting of advancements in numerical calculation and realtime implementation tools [8], the model predictive control (MPC) has featured as a highly beneficial and alluring control method in a variety of industry applications [9], [10].…”

The performance enhancement of the Induction Motor (IM) is a crucial and strenuous task. The Direct Torque Control (DTC) method is a common control strategy for boosting the IM drives and wildly implemented due to its merits including insensibility to motor parameters and fast response. However, the main shortage of the traditional DTC method is that it may lead to large flux and torque ripples. In this regard, this paper proposes an efficient control method called a Finite-State Predictive Torque Control (FS-PTC) which is based on multi objective optimization technique to overcome the shortage in the conventional DTC method. In addition to that a ranking approach is presented to assign the weighting factor in the cost function which directly affects the performance of system. The proposed ranking approach is based on elimination the weighting factor by replacing the single cost function with two different cost functions. The proposed FS-PTC is applied and tested using the dSPACE environment to validate its effectiveness and efficacy. From the experimental simulations, the performance of system is enhanced considerably where the torque and flux ripples are reduced with maintaining a constant switching frequency compared to the conventional DTC.
