The work aims to optimize the control system of the frame-making machine of paper angle bead, regarding the control requirement of dual synchronous tracking of the speed and position in the fixed-length punching and cutting process of the frame-making machine. The equipment and working principle were introduced. The control model and mathematical model were analyzed and optimized. S curve was introduced in the asynchronous region for acceleration and deceleration, and the external interrupt mode for tracking control was used. Finally, Matlab was used to simulate the control curve. The control model optimization made the cutter track more accurate, the mathematical model optimization made cutter position and speed control more accurate, and the external interrupt mode realizedtracking control. By Matlab simulation, the curve of the tracking coefficient K was continuous without any step change. The control requirements of dual synchronous tracking of speed and position were satisfied. Practical application shows that, frame-making machine of paper angle bead has high control precision and good real-time control. With the designed S-curve acceleration and deceleration control method, the noise and vibration are reduced when the frame-making machine of paper angle bead is punching and cutting at high speed, and the service life and processing accuracy of the equipment are improved.
