Abstract EN
An online robust fault detection method is presented in this paper for VAV air handling unit and its implementation.
Residual-based EWMA control chart is used to monitor the control processes of air handling unit and detect faults of air handling unit.
In order to provide a level of robustness with respect to modeling errors, control limits are determined by incorporating time series model uncertainty in EWMA control chart.
The fault detection method proposed was tested and validated using real time data collected from real VAV air-conditioning systems involving multiple artificial faults.
The results of validation show residual-based EWMA control chart with designing control limits can improve the accuracy of fault detection through eliminating the negative effects of dynamic characteristics, serial correlation, normal transient changes of system, and time series modeling errors.
The robust fault detection method proposed can provide an effective tool for detecting the faults of air handling units.
