Robust Nonlinear Speed Control of IPMSM Using the Synergetic Approach for Electric Vehicle

In this study, we investigate the performance of Interior Permanent Magnet Synchronous Motors (IPMSM) used in electric vehicles under two different control methods: Proportional-Integral (PI) control and synergetic control (SC). IPMSM are widely employed in electric vehicles due to their high efficiency, power density, and wide speed range. Efficient and precise control of IPMSM is crucial for improving the overall performance of electric vehicles (EV). We provide a comprehensive overview of both synergetic control and PI control, highlighting their key components and principles. A comparative analysis of the two control methods is conducted, focusing on their impact on IPMSM performance in terms of efficiency, torque control, and speed control. Simulation results are presented to validate the effectiveness of each control method and to demonstrate their respective advantages and disadvantages. Based on the comparison, we discuss the preferred control method for IPMSM in electric vehicle applications.
