To improve the speed tracking precision of corrugated cardboard crosscut machines and reduce its shearing error. A speed control system was designed based on the fuzzy control. The working principle of cross-cutting machine was introduced. Aimed at the speed tracking control, a control algorithm was expounded. A speed tracking controller was designed based on fuzzy control to solve problems such as nonlinearity, inaccurate mathematical model, mainly including fuzzification, membership functions and fuzzy rules. The experimental platform was set up with DSP as the core. The hardware circuit structure was also expounded, including IPM module, driving isolating circuit, speed and position detection circuit, etc. The control system still could obtain speed response in a short time even if interference existed. It also had small synchronous speed deviation and high tracking accuracy. The control system described can improve the shearing efficiency and reduce the shearing error. It meets the design requirements of cross-cutting machine.
