An DQPSO-Based Multi-Fault Diagnosis for Radar Auto-Erecting System with the Extended D-Matrix

This paper analyses the shortcomings of traditional dependency matrix (D-matrix) and presents an improved extended D-matrix about the multi-fault diagnosis for the radar auto-erecting system. The function, fault mode and test points of auto-erecting system have been provided firstly. Then, we propose the logical switch unit into the graphical model to describe the actual actions of system before or after a fault. Then, a new fault-switch D-matrix is established to clarify the actual correlation between fault modes and test points. By studying the discrete quantum -behaved particle swarm optimization (DQPSO), the multiple fault diagnosis method is proposed for auto-erecting systems, supporting the global and effective optimal searching of diagnosis result.
