| Abstract: | In order to control the hot forging process and the quality of forgings, the artificial neural network (ANN) is trained off line by using finite element numerical simulation of bulk forming process and by using the method of electricity simulation, the complex ANN model is created by means of simple analog circuits. Thus, the mapping is completed from bulk forming process to analog circuit. The adaptive model following control system is made up through paralleling the analog circuit with adaptive control system. |
