【Abstract】 The robot driven by hydraulic is a typical electr-hydraulic servo system. The non-linearity,character varing are commen in this kind of sysytem. This paper makes a mathemaic model with neural networks and introduces a new kind of control method which can be used in robot control system. This control method using neural networks jointed with fanction,and has self-learning ability. It is suitable for the curve tracing problem. The construction of this control emphasizes the ability of the knowledge; the learning rule of the networks is based on PD. The result of the calculation is not used to the control system directly. It correct the controller accoding to the error and the differential of the system output. Simulation and experiment show that the mathematic model is right and the control method is effective.更多还原
