Abstract: The problem of electro-hydraulic servo control based on neuro-fuzzy hybrid technique is studied. Integrated advantages of neural network and fuzzy logic technique, a neuro-fuzzy controller is proposed. It has abilities of automatical knowledge acquisition, distributed information storage and quick reasoning and decision-making. An on-line learning algorithm is also given. The controller is adopted in a typical electro-hydraulic servo system, satisfactory effects are obtained. Neuro-fuzzy hybrid technique has important value for development and demands (more complex systems and high performance control) of electro-hydraulic servo control.
