Reliability Analysis of Electric Aircraft Drive System with Feedback Loop

doi:10.3969/j.issn.1000-1093.2022.02.023

Abstract

Abstract: Due to the existence of feedback loop, the reliability of electric aircraft drive system cannot be analyzed by using GO methodology directly. If the feedback loop is disconnected directly, the accuracy of the analysis results will be reduced. To solve this problem, a reliability analysis method of system with feedback loop is proposed by establishing Boolean equation. The feedback signal is set as a system input, and Boolean equation with the feedback signal can be established according to the signal flow direction and the operational rules of GO operators.The expressions of each feedback signal are derived by using Boolean equation and the equations of other feedback signals, and then the analysis results of system reliability is obtained. For the PMSM drive system of an electric aircraft, the system reliability model is established based on GO methodology. The two cases of system without and with feedback loops are analyzed and compared. The results show that the proposed method for feedback loops is feasible, which can improve the accuracy of analysis results and extend the application range of GO methodology.
