Abstract
A system for distributed multi-axis motion control includes a controller having a memory configured to store a control program and a processor configured to execute the control program. A desired motion trajectory is determined for a multi-axis system having multiple axes, and an axis command is generated for each of the axes as a function of the desired motion trajectory. The system also includes multiple motors and multiple motor drives. Each of the motors corresponds to one axis for the multi-axis system, and each of the motor drives controls at least one of the motors responsive to receiving the axis command for the corresponding motor. Each of the motor drives also determines a motion state for a link driven by the motor as a function of the axis command and transmits at least a portion of the motion state to another motor drive controlling another axis.
