Modeling and Implementation for Embedded DC Motor Ethernet Control System

In this paper, a model of Embedded DC Motor Ethernet Control System is proposed with analysis on transmission time delay and data packet dropout. Based on this model, the ECS is described as a two-state asynchronous dynamical system with output feedback control and then implemented on a platform which uses a PC as a central controller and an ARM9 kit as a remote controller. As a key part of developments, embedded programs including client program and Linux Module are realized on the kit. The platform is proved to be flexible to run different control algorithms and extensibility to add nodes. The experiments and results demonstrate the validity of the system.
