Servo Real-Time Control Network Design of Dynamic Priority Control Strategy

Compared to conventional control systems, network control system has advantages in lower installation costs and easier maintenance. Regarding computer control, a design for network control system is proposed based on CAN (Controller Area Network). Through optimizing the design of the network adapter, computer centralized control algorithm can be applied to a simple network control. After analyzing the strategies of the network control interface, the real-time characteristics of CAN has been studied. A multi-channel control scheme for CAN is proposed. Then the structure of CAN is designed, which is constituted by CAN card and node controller. Finally, practical performance and high reliability of the system is proved by experiments.
