摘要
In this project, combined with the process of heat transfer for plate-fin heat exchangers in aircraft environmental control system, we attempt to establish mathematical model based on inputs and outputs of heat exchangers. Then, the relative observer is given to generate residuals by the comparison of the outputs between heat exchangers and observers. Furthermore, fault information is obtained from the evaluation of residuals. Finally, simulation results show that the proposed scheme for heat exchanger failure detection is effective; it can be regarded as the theoretical basis of relevant engineering technology.
