Enhancing Safety and Dynamic Control in Hub Motor Electric Vehicles through ASC and PIR Current Control

Hub motor electric vehicles are a revolutionary technology that integrates electric motors into the wheel hubs, offering efficient power transmission and motion control. The increasing demand for hub motor electric vehicle performance has led to the development of fault tolerance and self-recovery technologies, particularly concerning safety. This paper addresses dynamic control issues and proposes a Proportional Integral-Resonance (PIR) closed-loop current controller for hub motors, specifically to suppress surge current after active short-circuit (ASC) engagement. The research demonstrates the effectiveness of the PIR control strategy in controlling surge current and improving vehicle stability during hub motor restarts. The simulation study showcases the benefits of PIR control over conventional PI control in terms of current tracking accuracy and dynamic response. The results indicate that PIR control significantly reduces signal amplitude errors, ensuring smoother operation and improved dynamic performance.
