Electric vehicles (EVs) achieve optimal performance by using reliable and high-efficiency motor control systems. Among the numerous motors, brush-less direct current (BLDC) motors are preferred in EV applications because of their efficiency and torque characteristics. This paper describes the design and implementation of cascaded Proportional Integral (PI) controllers suitable for EVs using BLDC motors. This multi-loop hierarchy has the superior characteristics of limiting torque ripples in varying load conditions. The system is modeled using MATLAB/Simulink®. The simulation results imply that the proposed method reduces settling time, and improves accuracy compared to standard single-loop controllers. Hence these results demonstrate significant improvements in EV performance by validating the effectiveness of the proposed cascaded PI controllers in achieving precise position and speed regulation.

摘要

Electric vehicles (EVs) achieve optimal performance by using reliable and high-efficiency motor control systems. Among the numerous motors, brush-less direct current (BLDC) motors are preferred in EV applications because of their efficiency and torque characteristics. This paper describes the design and implementation of cascaded Proportional Integral (PI) controllers suitable for EVs using BLDC motors. This multi-loop hierarchy has the superior characteristics of limiting torque ripples in varying load conditions. The system is modeled using MATLAB/Simulink®. The simulation results imply that the proposed method reduces settling time, and improves accuracy compared to standard single-loop controllers. Hence these results demonstrate significant improvements in EV performance by validating the effectiveness of the proposed cascaded PI controllers in achieving precise position and speed regulation.
