Abstract: By a combination of the strong Reasoning reasoning power possessed by the fuzzy control and learning ability in the neural network, a new type of structure of the neural network bed ac controller is proposed. To meet the need of real-time calculation in the contiol process, the TMS320C30 high speed digital signal processor (DSP) is adoptal as the control and process unit, and the real-time fuzzy neural network control is successfully accomplished in the electrohydraulic position control system.
