Based On The Can Bus Electric Steering Gear Distributed Computer Control System Design

In this thesis, the theory and protocol of FIELD BUS and CAN BUS have been explained, and their excellence and foreground in application have been analyzed; the structure and development direction of the distributed computer control system have been researched; and the design of servo motor's distributed computer control system by CAN BUS have been completed, too.During this period, the hardware used to communicated with the central computer in CAN BUS have been designed, tested and accomplished; the hardware for controlling the servo motor by structure changing controller have been designed, tested and achieved; and the software used in this system have been debugged and compiled, too.Lastly, the project, the servo motor's digital controller, and its designing difficulty and detail have been researched.The product can be used in common factory and special environment.
