Abstract

To achieve a better position accuracy control for flexible nozzle system under different swing amplitude, swing frequency and operating pressure, an electro-hydraulic servo mechanism- neural network model is constructed in this paper. And it is compared with experiment results as well as other physical models. The researches show that the model results of electro-hydraulic servo mechanism-neural network model have a good agreement results with experiment results. The model has good simulation accuracy, generalization ability and can provide accurate dynamic model for flexible nozzle control.

Key words： flexible nozzle; electro-hydraulic servo mechanism; neural network model; hysteresis loop
