Parameters identification of direct thrust control system using wavelet transform

Wavelet analysis is used in parameters identification in this paper, because of the time frequency location characteristic and multi-scale ability of wavelet transform and multi-resolution analysis. Then this paper compares the neural network with wavelet transform to identify the direct thrust control system parameters, and obtains the results are shown that the wavelet transform is further suitable for parameters identification. The simulation results of direct thrust control system show the identifier that is based on wavelet transform can precisely measure the value of parameters and efficiently improve the low-speed performances of direct thrust control system.
