Robust Data-Driven Design for Fault Diagnosis of Industrial Drives

Abstract: Due to the presence of actuator disturbances and sensor noise, increased false alarm rate and decreased fault detection rate in fault diagnosis systems have become major concerns. Various performance indexes are proposed to deal with such problems with certain limitations. This paper proposes a robust performance-index based fault diagnosis methodology using input–output data. That data is used to construct robust parity space using the subspace identification method and proposed performance index. Generated r… Show more

“…The fault detection rate of the proposed diagnostic scheme consistently performs higher as compared to both conventional diagnostic approaches. Quantitative comparison is provided in table 1, demonstrating the superiority of the proposed approach in terms of fault alarm rate and false alarm rate when compared to the conventional approaches [32,40]. Residual plots for sensors and actuators fault using conventional [32,40] and proposed approach.…”

“…Quantitative comparison is provided in table 1, demonstrating the superiority of the proposed approach in terms of fault alarm rate and false alarm rate when compared to the conventional approaches [32,40]. Residual plots for sensors and actuators fault using conventional [32,40] and proposed approach. It is noticed that the proposed approach stands out as a computationally efficient solution for nonlinear dynamic systems, with the strategic use of pre-computed parity vectors being a key contributing factor.…”
