This research study introduces a novel approach for developing a vector fault-tolerant control system for the Doubly Fed Induction Generator, employing an adaptive observer. The observer uses the statistical analysis of stator terminal currents and voltages to detect the mechanical speed and flux components. A straightforward method is employed to adjust the mechanical speed. A stability study utilizing Lyapunov theory ensures the observer’s closed-loop stability. The mechanical speed is used to rectify the controllers. To assess the suitability and resilience of this control mechanism, we examine the Doubly Fed Induction Generator operation in the presence of unbalanced load conditions, a common occurrence in real-world scenarios. Our research will focus on the investigation of vector control theory through the synthesis of classical controllers. The simulation results are shown in MATLAB software to check how reliable, consistent, and valid the suggested fault-tolerant control method is for Doubly Fed Induction Generator-based vector control.
