Research of Fault Diagnosis and Predication System Based on Self-adapting Infinity Impulse Response Filter Model

To meet the need of testability and diagnostic design for certain equipment,a fault predication and diagnostic system is put forward based on self-adapting infinity impulse response(IIR) filter in the paper.In the system,a self-adapting IIR filter is put forward as the fault predication model and an improved particle swarm optimization algorithm is used to accelerate the speed of convergence.The system has high reliability,strong engineering practicality and easy configuration.
