| Abstract: | The structure and principle of wavelet neural network (WNN) is described in this paper. After discussing the main sensor faults of air-conditioning unit in intelligent buildings, a wavelet neural network based approach is presented to diagnose these faults. The results of simulation by MATLAB and test of model show that in the same conditions the approach is better than that by BP network in the sensor fault detection, identification and accommodation. |
