Description
Summary:This paper aims to contribute to the fault-tolerant control of the current sensor. The system studied is a double star induction machine (DSIM) controlled by a robust control called Active Disturbance Rejection Control (ADRC). The proposed method makes it possible to detect, isolate, and reconfigure the fault in real time. The reconfiguration is based on the comparison between the values measured by the current sensors and the estimated values. Two voltage observers will be used to estimate the estimated currents, and these two observers are placed at the level of the converters. This method of fault-tolerant control (FTC) has the advantage of ensuring, even in the presence of a sensor fault, the continuity of the system’s operation and maintaining its performance at the desired level. The effectiveness of the FTC strategy proposed in this work is illustrated with simulations carried out under the MATLAB/Simulink environment.
