| Abstract: | In spray forming,obtaining accurate dimensional accuracy of a deposit is difficult because there are lots of disturbances in this process.Therefore,an intelligent fuzzy-PID controller(FPID),whose parameters are self-adjusted based on fuzzy inference,was developed to improve the accuracy of deposit dimension.The simulation results of the controller show that the override is low,and the error of steady state is better than PID controller.The experimental results show that the error between actual size and target value 5.5 mm is 0.22 mm,and the mean square root of error is 0.34 mm. |
