Abstract

To improve the fault-tolerant ability of switched reluctance motor (SRM) drive systems and ensure the braking performance of the electric vehicle driven by in-wheel SRMs, a novel fault-tolerant control method that includes the open circuit and the short circuit is presented in this study. First, a novel modular fault-tolerant power converter, which includes traditional driving topology and modular fault-tolerant construction, is built in accordance with the traditional half-bridge power converter. This novel converter provides an advanced fault-tolerant solution for the faults of SRM drive systems. Then, combined with the corresponding detection signals, a new fault detection method is presented for accurately detecting the faults of the system. Furthermore, a new fault-tolerant control method is proposed to improve the fault-tolerant ability of the system. Notably, the fault-tolerant process is completed by employing the circuit of the traditional power converter to replace the fault circuit of the modular construct when faults are detected. Moreover, simulation results are obtained and compared. The results indicate that the proposed method can ensure vehicle braking performance, including braking comfort, braking safety, endurance mileage, and braking stability. Finally, hardware-in-the-loop is conducted, and the results demonstrate the real-time performance and validity of the proposed method.
