A kind of modelling scheme based on ANN’s inverse model and EFRA(Exponential Forgetting and Resetting Algorithm) simulation for nonlinear system

It was an important method to identify and model for nonlinear system based on the system´s inverse model recently years. In order to model to complex, unknown and the indefinite nonlinear object, besides the nonlinear object was reversible, but also need reasonable modelling structure scheme and inverse model with good performance. Based on ANN´s (artificial neural network) nonlinear mapping performance, the modelling scheme based on ANN´s inverse model had been designed in the article. Used EFRA (exponential forgetting and resetting algorithm), the ANN´s inverse model had been trained on-line, and the ANN´s inverse model with satisfied identification request had been gotten. After massive simulation researches have been done, it is proved the modelling structure scheme is reasonable, the EFRA is effective to raise effect of identification and modelling and control performance.
