| Abstract: | A parameter identification method of time-varying system based on process neural network is proposed.Process neural network has non-linear,auto-learning,and auto-adaptable functions.It has time-varying input and output functions.The procedure neural network was proposed to identify the parameters for a time-varying three degrees of freedom system in the paper.The experimental result shows the effectiveness of the proposed method for a parameter identification of time-varying system. |
