Effects on Residual Stress of Electron Beam Welding of TC4 Al loy by Laser Phase Transformation Treatment

Lu Jinzhong,Zhang Yongkang,Kong Dejun,Ren Xudong,Zou Shikun,Wang Xichang

Strategic Study of CAE 2007, Volume 9, Issue 5,   Pages 72-76

Abstract:

  In this study,  an effective control method and strategy based on fuzzy neural network has been developed for gas injection pressure accurate control in gas-assisted injection. A fuzzy neural network controller with five layers and its control algorithm are established.  The learning ability of neural network is used to optimize the rules of the fuzzy logic so as to improve the adaptability of system.  The simulation of the system capability and three segmental injected pressure control are carried out under the environment of MATLAB and the results show that this theoretic model is feasible, and the control system has good characteristics and control action.
