Electric vehicle, Regenerative braking system, PID control
Abstract
The application of permanent magnet synchronous motors (PMSM) in electric vehicles (EVs) has become increasingly important, particularly in improving the efficiency of regenerative braking systems (RBS). However, traditional approaches to controlling PMSM motors have limitations in achieving both stability and fast response times under varying load conditions. Current methods often struggle to balance the trade-offs between overshoot, robustness, and system stability. In this study, the study proposes a PID-based control strategy to enhance the performance of PMSM motors in RBS applications. By modeling the motor dynamics and designing a PID controller with optimized gains, the system’s transient response was improved. MATLAB simulations demonstrated that the proposed method achieves faster response times, reduced overshoot, and improved steady-state stability. The results suggest that this approach can significantly improve the efficiency of RBS in electric vehicles, contributing to enhanced energy recovery and overall vehicle performance. This study provides a potential solution for overcoming the limitations of current PMSM control strategies and offers a foundation for future research in optimizing EV motor control systems.
