摘　　要：以提高工业锅炉运行的安全性和可靠性为目的,设计基于MATLAB的工业锅炉故障诊断系统.利用MATLAB强大的矩阵计算能力和函数调用功能,实现基于主元分析(PCA)的故障诊断算法,并通过OPC技术与锅炉集散控制系统(DCS)进行实时数据交互,完成在线故障监测与诊断.对传感器和执行器的故障模拟验证了系统的有效性.A fault diagnosis system based on MATLAB was de- signed in order to increase the operation security and reliability of industrial boiler. By means of the MATLAB computing en- vironment, a fault diagnosis algorithm based on principal compo- nent analysis （PCA） was realized via matrix computation and functions. The fault diagnosis system can exchange data withthe boiler distributed control system （DCS） utilizing OLE for process control （OPC） technology, so as to monitor the opera- tions and diagnose the fault on line. The effectiveness of the sys- tem is illustrated by simulating both the known sensor and actu- ator failures in the industrial field.
