Abstract：This paper analyzed the speciality and controlled requirement of the papermaking
machine. Based on these requisition, designed embedded controller and realized controlling the electricity of the Papermaking machine. And this paper designed embedded controller based on S3C2410, controlling feedback and velocity, relay system, building the network level framework based on PowerLink bus of this machine and realized controller hardware. At the same time, designed software system of the controller based on real-time operating system, and realized controlling.
