Safety Analysis of STPA-Based High-Power Electromechanical Drive Control System for More Electric Aircraft
摘要
Abstract
The common motor starter controller(CMSC)is an important equipment in the electromechanical drive control system of more electric aircraft,and improving its safety is of great significance for ensuring the continuous airworthiness of the aircraft.Taking the electric pump mode of the CMSC as the research object,an analysis of working principles and module division are conducted,formal modeling is carried out using UP-PA AL software,and system-theoretic process analysis(STPA)is implemented.The unsafe control behaviors and potential hazards causes between subsystems are identified,and based on model liveness verification and fault injection experiments,correction of causal scenarios is performed to ultimately construct a relatively compre-hensive safety control constraint list.Experimental results demonstrate that the proposed method facilitates the safety analysis of the CMSC,and formal modeling is used to help to reduce the interference of subjective human factors.The model exhibits high operational efficiency,while causal scenario analysis results indicate that the established safety control constraint list is accurate and can effectively cover failure scenarios.关键词
