Fault-Tolerant Drive Control Systems

Abstract

Fault-tolerant drive control systems (FTDCS) have emerged as critical technologies in industrial, automotive, and aerospace applications, where reliability and continuous operation are paramount. These systems are designed to maintain stable operation in the presence of component failures, such as sensor malfunctions, actuator faults, or power electronics anomalies. The integration of fault diagnosis, isolation, and reconfiguration strategies ensures enhanced system robustness. This review paper presents a comprehensive examination of fault-tolerant techniques for electric drives, including fault modeling, detection methods, and control strategies. Key methodologies such as redundancy, observer-based fault detection, adaptive control, and reconfigurable drives are discussed. Finally, challenges and future research directions in achieving highly reliable and efficient drive systems are highlighted.
