基于自适应数值滤波器的空调系统故障诊断
Fault Diagnosis on Air-Conditioning System Based on Adaptive Digital Filter
摘要
Abstract
As a part of the aircraft air management system, the air-conditioning system is the key controller to keep the cabin warm and comfortable. So the air-conditioning system fault detection and diagnosis is important to keep it in normal working states. At first,analyzed the structure of the air-conditioning system, and then the single-stage loop structure is built, and the mathematical model of each link is obtained as well. The adaptive digital filter method and the 3σr criterion are applied to the fault detection. And based on the adaptive digital filter and the mathematical model, the joint fault diagnosis method is proposed for fault location and fault type judgment. At last, this method is verified by the simulation experiments. And the results demonstrate that the Joint fault diagnosis method can be successfully applied to ffault detection and fault type judgment.关键词
