“…According to the current control module way of thinking, FOC works together with SMC to suppress the torque ripples in the inner loop current control [79]. For improving the performance of this controller from backlash nonlinear action, the high-frequency dither signals are injected in different types of modulation and enhance the motor system performance in EVs [80]. Similarly, it is possible to improve system performance by reducing electromagnetic torque ripples and enhancing current shape through THD by using of fuzzy logic concept [81].…”

In recent years, electric vehicles (EVs) have attracted a lot of attention and are rapidly growing trends today due to their ability to compete with and overtake fossil fuel-powered vehicles among all electrified transportation tools. The primary focus of EV evolution is on improving driving range and optimizing energy consumption, both of which are essential demands achieved through improved and developing motor performance. The brushless direct current (BLDC) motor is one of the most superior choices for dynamic applications in EVs, providing the highest power density and capability of any motor. BLDCs are gaining popularity in EVs not only for their high performance in speed and position controls but also for meeting the requirements of smooth torque maintenance with torque ripple mitigation. This paper provides an overview of various advanced control strategies, such as field-oriented control (FOC), direct torque control (DTC), intelligent control (IC), controlling input voltage (CIV), current shaping techniques (CST), model predictive control (MPC), and sliding mode control (SMC). These strategies are used to regulate the torque ripples produced in BLDC motors, aiming to achieve energy-efficient EV performance for various applications. Additionally, it describes a cloud-based control system coupled with electric motor drives to address challenges in predicting current vehicle conditions for improved power distribution between the motor and battery systems. Furthermore, recent concerns and difficulties in advancing torque ripple mitigation control strategies are highlighted, with comparisons and discussions for future EV research. Finally, an evaluative study on BLDC motor drive in EVs with different control strategies reveals its significance and potential outcomes.

This paper describes an approach to implement Field Oriented Control (FOC) using PID Controller for a brushless direct control (BLDC) motor. The research proposes reduction in total harmonic distortion of the supply current using space vector pulse width modulation technique. Minimization of total harmonic distortion becomes mandatory for a smooth operation in electric vehicle applications. As the harmonics are generated in the supply current, caused by non-linear load in E-Rickshaw. The lower, the value of total harmonic distortion givers better performance of the motor when operated under light load. Here the different strategies employed for controlling BLDC motor speed is analyzed and compared. It also proved that the space vector pulse width modulation technique improves the reliability due to the balanced switching frequency achieved from the solid-state switches in the inverter. Through simulating, the proposed control strategy is analyzed and compared with the existing techniques results in smooth change in current during sudden loading, which improves system performance and as a result the torque ripple gets minimized. The comparative study was made in the Matlab/Simulink 2019b, by designing the mathematical model of motor, inverter and the switching sequence, and the max-min algorithm for the SVPWM.
