The Neural Network

The flow press servo valve has very special work principle, and it now is widely used in the electro-hydraulic force servo system as main and kernel part. According to its special work principle, electromagnetic basic theory and the flow continuity equation, the mechanics analysis of every main part of the flow press servo valve was finished; the author built the mathematic model of the flow press sever valve. During the process of building model, the author took into account the load torque on the torque motor keeper and the total load torque of torque motor. On the other hand, the neural network intelligent control strategy was used in the force servo system to improve the whole system performance. The mathematic model of the electro-hydraulic force servo system controlled by the flow press servo valve with the neural network control strategy was built. The simulation curves and the experiment curves were accord compared by system simulation and experiment results, so we can know also that the mathematic model of the flow press sever valve and the electro-hydraulic force servo system controlled by this kind of valve with the neural network intelligent control strategy are correct.
