A novel metaheuristic model-based approach for accurate online broken bar fault diagnosis in induction motor using unscented Kalman filter and ant lion optimizer

Abstract: This paper introduces a novel metaheuristic model-based scheme for fault monitoring in squirrel cage induction motors (SCIMs). This method relies on the combination of the ant lion optimizer (ALO) and the unscented Kalman filter (UKF) to detect and quantify the number of broken bars. Contrary to the UKF-based fault diagnosis, the improved ALO-UKF algorithm tunes optimally and automatically the noise covariance matrices Q and R, which reduces the estimation errors, and then obtains an effective and accurate fau… Show more

“…It is also well known that the control performance is dependent on accurate knowledge of the control variables/states that are generally obtained by using the observers instead of direct measurements leading to an increase in cost and hardware complexity. Moreover, the correct estimation and update of the parameters to both the control system and the observer itself results in enhanced performance for field-oriented control (Adamczyk and Orlowska-Kowalska, 2022), model predictive control (Zerdali and Demir, 2021), fault-tolerant control (Raisemche et al, 2016; Sobanski and Orlowska-Kowalska, 2017), and fault diagnosis (Namdar et al, 2022; Rayyam and Zazi, 2020). However, due to the frequency and temperature-dependent variations in rotor and stator resistance ( R r and R s , respectively), the flux level-dependent variation in inductances, and unknown mechanical parameters, it is still an open area to research for academic people and industries concentrating on the state and parameter estimation of IMs.…”
