Abstract:
A method for constructing a quantum echo state network model for an aero-engine fault early-warning. The method comprises: first, quantizing time series data of an aero-engine; then, using quantum state data as an input of a quantum network of a first layer and subjecting same to the action of a quantum recursive circuit, and then obtaining a probabilistic output by means of quantum measurement and transferring same to a reservoir of an echo state network of a second layer, so as to obtain a high-dimensional intermediate state; and finally, performing computation only once by using a least squares method, such that a weight matrix of an output layer can be obtained, thus completing network training. A trained quantum echo state network model is applied to aero-engine fault prediction, thereby providing relatively high-accuracy operation state prediction data of an engine at a future moment. In the present invention, a quantum controlled NOT gate is utilized to realize an entangled state, so as to approximately represent a possible coupling relationship between original input data, and a quantum rotation gate is set to be an adjustable parameter of a quantum network of a first layer, such that the distribution of data can be adjusted; moreover, an echo state network layer can exert the computational advantage of fast computation and completion of a final model with one-step training.
