Abstract:

Electro-mechanical servo system with permanent magnet synchronous motor as the main actuator has to modify the control parameters frequently in order to realize the optimal control of the system. If the parameters are modified by modifying the source code, it will lead to many versions of the software, version control low efficiency, affecting the progress of development, especially in some special occasions preventing servo-controlled driver open cover (open the shell) operation, it will not be able to update the software or adjust the control parameters. A parameters online binding method of servo system based on CAN bus was presented. By using the CAN bus communication between the host computer and the digital signal processor, addressing and reading of the Flash and RAM resources of the digital signal processor write control were realized to complete the control parameters of servo system online binding and read back calibration. The practical engineering application proves that the method is convenient, efficient and reliable, and provides a good solution for quick application of electromechanical servo system.
