A fault diagnosis system based on MATLAB is designed for increasing the operation security and reliability of industrial boiler. Under the MATLAB computing environment, a fault diagnosis algorithm based on principal component analysis (PCA) is realized via matrix computation and functions. The fault diagnosis system can exchange data with the boiler distributed control system (DCS) utilize OLE for process control (OPC) technology and monitor the operations and diagnose the fault on line. The effectiveness of the system is illustrated by simulation of known sensor and actuator failures in the industrial field.
