Abstract :
Design of networked servo control system based on CAN bus is proposed. Systematic structure of servo control system and the servo node implementation are introduced. Software hierarchical structure is analyzed in brief. Moreover, Software frame and control loop of servo node are illuminated, and especially the offset in current control loop is analyzed and the compensating method is proposed to ensure zero point of motor current to be accuracy.
