Problems solved by technology

However, the intelligent verification test methods or methods for the aircraft electromechanical PHM system are still in the academic research stage, and there is a lack of practical verification test design guidance.
On the road of exploring the verification test method of the aircraft electromechanical PHM system, due to the complex internal composition and cross-linking relationship of the electromechanical management system, there are many characteristic parameters that characterize the electromechanical management system, and the transfer relationship of the characterization parameters within the electromechanical management system is intricate.
