To the six-degree-of-freedom hydraulic parallel robot system with big uncertainties and random disturbances, which eigenparameters vary greatly with the working conditions and surroudings, the neuron control method using a fuzzy transfer is proposed to control the hydraulic active joint of the robot system in this paper. In this method, the fuzzy transfer is designed by using a formultion fuzzy algorithm. The simulation resutls show that this new model-free control method has very strong robustness and adaptability as well as good disturbance-resistance and satisfied performances. It is useful for hte real-time control of the hydraulic parallel robot.
