Abstract:

A validation system of prognostic and health management system for aviation electromechanical actuator(AEMA) was designed for validating and evaluating the intelligent algorithms and reasoning models of prognostic and health management (PHM) system. By analyzing the failure mechanism of AEMA, the modeling and fault injection methods of electrical machine, common fault data source were presented as well as the hardware architecture and general software operating environment based on component-based architecture of the verification prototype system were designed, in which various PHM algorithms and system models could be loaded, called and evaluated, simultaneously, the information of verification and evaluation could be online real-time displayed.
