Research on Fuzzy Self-Tuning Control Method of High Precision Tool Grinder Pendulum Shaft
To address the high-precision requirements for the rotation motion of tool grinder pendulum shaft during precision tool grinding processes,a novel high-precision tool grinder pendulum shaft and its control system were designed.Firstly,a systematic mathematical model was established based on the designed me-chanical structure of the pendulum shaft.Secondly,to meet the requirement of stable rotation for different grinding requirements in the project and solve the problem that conventional PI control cannot achieve pre-cise speed control of such time-varying systems,a fuzzy control strategy was introduced to adjust the PI control parameters.Finally,the pendulum shaft system was simulated and verified using MATLAB/Simu-link modules.The results showed that the pendulum shaft system with fuzzy PI control has good speed tracking performance,with an overshoot of less than 1%,and good robustness,which can meet the require-ments for high-precision tool grinder pendulum shaft motion control accuracy in engineering applications.
