【Abstract】 The composition and working principle of the multi-station nut forging conveying equipment are introduced,and the position control system of the equipment is analyzed to establish the mathematical model of the overall position control system.According to the characteristics of the position control system,the position control algorithm of adaptive fuzzy PID is proposed.On this basis,the overall simulation model of the position control system is established by Matlab/Simulink. The simulation results show that the proposed position control algorithm solves the problems of large overshoot,weak anti-interference ability,large parameter influence,slow response speed and poor steady-state accuracy in the position control process,which makes the position control system have good dynamic characteristics and static characteristics.更多还原
