Abstract: Autonomous Fault-Tolerant Control Architecture for Multi-Phase Motor Drive Systems in Industrial Automation is the proposed invention. The suggested invention includes a multi-phase electric motor, a power electronic inverter, a sensing unit, a fault diagnosis module, a model-free predictive control module, an adaptive current redistribution module, a switching-vector selection module, and a supervisory reconfiguration module. Real-time data such as phase currents, inverter statuses, DC-link voltage, rotor position, motor velocity, and load-associated metrics are collected and analysed to detect irregular operating circumstances. A model-free predictive controller evaluates the immediate current response based on observed input-output dynamics and identifies an optimal switching action without necessitating ongoing reliance on a precise mathematical representation of the motor. Upon identifying and categorising a defect in a phase, inverter-switch, or sensor, the supervisory module autonomously segregates the impacted control pathway and produces adjusted current references for the operational healthy phases. The predictive controller then determines switching states based on a multi-faceted cost function that includes current tracking inaccuracy, torque deviation, phase-current imbalance, switching effort, and thermal limitations. The design facilitates independent shifts between optimal and resilient operating modes while preserving torque and speed control, thus enhancing operational continuity, dependability, and fault recovery of industrial multi-phase motor drive systems.
