【Abstract】 In order to solve the problem that the temperature of melten pool can not be controlled during. Powder overlaying welding, a self_learning controller based on fuzzy CP network is developed by combining fuzzy CP network and the theory of self_learning fuzzy control. With self_learning algorithm, the controller can obtain sufficient information and optimize its control characteristics. The controller can be applied to control of nonlinear time_variational uncertain process. When Powder overlaying welding maching is operating, the controller can control the melten pool in the set region of temperature, and a good quality layer is formed. The error of thickness of layer of 300mm in length is: Δδ≤0.1mm.更多还原
