英文摘要：

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.
