Abstract:Aiming at the paper web accuracy problem of paper cutter， using a combination plan of frequency conversion control and servo control， a paper cutter hybrid electric control system with STM32 single-chip microcomputer as the core was designed. The speed of the paper feed roller was obtained via combination of M/T speed measurement and Kalman filtering， which was used to reduce the collection error of the paper feed roller speed. The experiment results showed that the method could obtain the speed of the paper feed roller motor and the paper cutter motor in real time under high speed. According to error analysis results， the paper cutter accuracy had reached ±1 mm， proving the feasibility of the control system.
